摘要： An optical system has an extended boresight source including a boresight light source that produces a light beam, a condenser lens that receives the light beam from the boresight light source, a spatial light integrator that receives the light beam from the condenser and mixes the light beam to reduce its spatial inhomogeneities, a constriction through which the light beam from the spatial light integrator is directed, and a collimator that receives the light beam which passes through the constriction and outputs a boresight light beam. The boresight light beam is typically provided to a sensor imager that uses the boresight light beam to establish its centroid.

摘要： A kinoform optical element (KOE) has different surface relief heights in different zones of the kinoform surface, in order to optimize the first order diffraction efficiency in each zone. By increasing the first order diffraction efficiency, noise as well as ghost image problems may be reduced and contrast and resolution may be enhanced. In an exemplary embodiment, each zone, or even different areas of the same zone, has a non-constant step height that is preferably defined by a predetermined relationship between an optimal step height and an associated predominant angle of incidence associated with that particular zone or area. In the case of an optical system having a relatively large aperture and a relatively narrow field of view, each point of the KOE sees the entire image; the associated predominant angle of incidence at that point may be defined by a so-called "marginal" ray from the center of the entire image space (i.e., on the optical axis and at the effective "middle" of the usable depth of field). In the case of an optical system having a relatively small aperture and a relatively wide field of view , each point of the KOE sees only a portion of the image; the associated predominant angle of incidence at that point may be defined by an exemplary ray from the portion of the image space that is visible from that point. Since the optimum surface relief is dependent on the angle of incidence of the radiation relative to the orientation of the surface, diffraction efficiency can also be optimized by providing the kinoform with a non-planar surface contour such that all the predominant rays are normal to the active surface, in which case all the steps may have the same height.
摘要翻译： Kinoform光学元件（KOE）在kinoform表面的不同区域中具有不同的表面浮雕高度，以便优化每个区域中的一阶衍射效率。通过增加一级衍射效率，可以降低噪声以及重影图像问题，并且可以提高对比度和分辨率。在示例性实施例中，相同区域的每个区域或甚至不同区域具有非恒定台阶高度，其优选地由最佳台阶高度与与该特定区域相关联的相关联的主要入射角之间的预定关系限定，或区。在光学系统具有相对较大的光圈和相对较窄的视野的情况下，KOE的每个点看到整个图像; 在该点处的相关联的主要入射角可以通过从整个图像空间的中心（即，在光轴上和在可用景深的有效“中间”）的所谓“边缘”射线来定义，。在光学系统具有相对小的孔径和相对宽的视场的情况下，KOE的每个点仅仅看到图像的一部分; 可以通过从该点可见的图像空间部分的示例性射线来定义在该点处的相关联的主要入射角。由于最佳表面浮雕取决于辐射相对于表面的取向的入射角，所以衍射效率也可以通过提供非平面表面轮廓的kinoform来优化，使得所有主要的光线垂直于活动表面，在这种情况下，所有步骤可能具有相同的高度。

摘要： A helmet/head mounted display including a display image source and a reflective visor for each eye. The image source includes a fiber optic cover plate with a planar input surface and a curved output surface which has curvature providing the correct curvature. The image source further includes a self-emitting device such as a field electrode display or electroluminescent device, or a polymer dispersed liquid crystal (PDLC) sandwiched between a thin, sharply tapered fiber optic plate and the fiber optic cover plate. For the PDLC image source, back light illumination is introduced through the tapered fiber optic plate, passes through or is scattered by the PDLC and then through the fiber optic face plate to the visor, for reflection to the observer's eye. The fiber optic face plate is constructed with a very low numerical aperture. The fibers of the cover plate are oriented toward the eye as seen in the reflection from the visor to reduce undesirable reflected light. No lenses or beam splitters are in the light path between the image source and the visor.

摘要： An improved helmet visor display comprising three elements, including a tilted combiner, a refractive/diffractive relay module, and an image generator. The tilted combiner is a reflective-type combiner having either a spherical surface shape or a generalized aspheric surface shape. The relay module comprises a front-end collimating lens group, a pupil lens group in the middle, and a rear-end focusing lens group. The collimating lens group is comprised of one refractive doublet and one refractive-diffractive optical element. The combination of the refractive doublet and the refractive-diffractive optical element corrects for primary and secondary axial chromatic aberration, and significantly reduces higher order aberration as a result of power reduction in most lens elements. The pupil lens group comprises a conic or aspheric lens which reduces spherical aberration and enlarges the eye pupil. The focusing lens group comprises a refractive doublet and a wedge that relays the light emerging from the pupil lens group onto the image generator. A crown-flint refractive doublet in conjunction with a diffractive optical element may be employed in the focusing lens group to reduce primary and secondary lateral chromatic aberration and chromatic distortion. The wedge is used to reduce axial coma introduced by the tilted combiner.

摘要： A virtual image display (VID) optical system that is very compact and has a wide field of view. The present optical system has good image quality, has simple optics, is very compact, provides wide field coverage, and has very large field overlaying. The system comprises a combiner and a catadioptric relay group disposed along an optical path between a cathode ray tube and an operator. The virtual image display system of the present invention is adapted to enlarge an image of the cathode ray tube viewed by the operator. The catadioptric relay group is typically comprised of a concave mirror and one refractive sub-group with at least one lens, and provides excellent image quality over a very wide field of view. The concave mirror contributes positive optical power to the system, thus providing for a compact optical system. The concave mirror may be tilted and/or decentered to balance the asymmetric aberrations generated by the combiner. The concave mirror may also have an axially symmetric or generalized surface shape to provide for aberration balance. The concave mirror and combiner cooperate to balance the field curvature introduced by a refractive shape of the relay group. The refractive group of the relay may also be tilted and/or decentered to reduce residual asymmetric aberration.

摘要： Disclosed is an apparatus (10) for null lens testing of an optical element (20). This apparatus incorporates both refractive (32, 36) and diffractive (30, 34) optical elements to create a null lens testing apparatus (10) tuned to two separate wavelengths. By combining or superimposing the interference patterns from the two wavelengths in an interferometer (12) using the two-wavelength holographic technique, the null lens testing apparatus (10) can desensitize the tests such that a single null testing apparatus (10) can be used to test an optical element (20) from its early fabrication stages to its final polishing stages.

摘要： A beam control system and method. The system includes an illuminator for providing a first beam of electromagnetic energy at a first wavelength; a source for providing a second beam of electromagnetic energy at a second wavelength; and an arrangement for compensating wavefront errors in the second beam using a bias representative of a comparison between the first wavelength and the second wavelength. In the illustrative embodiment, the arrangement includes a processor which corrects wavefront errors using a bias representative of a difference between said first wavelength and said second wavelength. In the disclosed application, a target wavefront sensor is included and the laser is a high-energy laser beam. The wavefront errors include a chromatic aberration and the errors are compensated using a deformable mirror and a correction algorithm executed by an adaptive optics processor. In one alternative embodiment, the errors are compensated using an optical aberration corrector. The aberration corrector may be a holographic optical element or other suitable device. In another alternative embodiment, the errors are corrected with the above embodiment in combination with the use of “woofer” and “tweeter” correcting elements with the woofer being a long stroke low frequency element and the tweeter being a short stroke high frequency element.
