摘要： A high concentration photovoltaic (HCPV) optics are described. In one example, an HCPV device can include a frame and a solar sensor cell attached to the frame. The solar cell can be configured to receive an optical beam and can further be configured to convert solar energy in the incident optical beam into electrical energy or power. The HCPV device can further include a non-imaging freeform optical device. The optical device can have an asymmetric surface profile with a predefined surface normal arranged to direct incident optical beams toward an entire solar sensor cell surface area. The freeform optical device can have a larger diameter than the solar sensor cell. Also, the freeform optical device can have an asymmetric surface profile shaped to concentrate the incident optical beams onto the solar sensor cell.

摘要： A three-dimensional (3D) surface profile measurement method and apparatus uses projected energy with a known spatially varying wavelength distribution over the surface of objects in a scene. The varying wavelength of the light corresponds to the angle at which the light is emitted from a light source. Given this correspondence, light reflected from the scene can be identified by wavelength as to angle at which it was emitted. Triangulation can then be used to determine the distance to the point in the scene from which the detected light is reflected. When performed over a number of points on the scene, a three-dimensional profile of the scene can be generated.

摘要： A process and system for displaying large (more than 1 million voxels) volumetric 3D images gives substantially higher resolution than is achievable with prior art techniques. The process and system utilize a sequence of helical slices of a 3D data set to generate a series of 2D images on a reflective surface of a light modulator. The series of 2D images generated on the light modulator are projected into a volumetric 3D-space display using an illumination light source and projection optics. Voxels in 3D space are illuminated for each 2D projected image, each voxel being located at its corresponding spatial location such that the 3D image thus generated can be viewed from any angle in a walkaround fish-tank manner without utilizing any viewing aids.

摘要： The target of the present invention is to provide an automatic high speed, low-cost, multi-mode three-dimensional(3D) surface profile measurement method. This method exploits the projected energy with a known spatially distributed wavelength spectrum on the surface of objects in the scene. The unique wavelength is encoded with geometry information of a unique projection ray of the radiation energy in 3D space. This wavelength of the projected energy is detected by a 2D image sensor array that is able to uniquely distinguish the wavelength of the radiation energy at the points of interest on the scene. The projection geometry information is recovered by using a color match scheme and the range values associated with every pixel of the 2D image sensor will be calculated through a straightforward triangulation algorithm. Full frames of 3D range images can then be obtained directly at the frame acquisition rate of the 2D image sensor array. The color ranging method eliminates the time consuming corresponding feature finding problem of normal binocular 3D imaging systems. Therefore, it is suitable for high speed, real-time measurement automation. Since there are no mechanical moving parts in our color ranging method, the mechanical design can be very simple and reliable. All components in this system are available off-the-shelf which leads to low cost. With the active light source being turned on or off, the same color camera can provide normal intensity images as well as 3D range data. This multi-mode capability greatly simplifies the problems of multiple sensor integration and sensor data fusion. Depending on the applications, the scope of the color spectrum of the energy projector can be selected from UV, visible, or IR light region. The Color Ranging method is not based on a laser therefore there is no "eyes safe" problem. This is certainly a desirable feature enable this system to be used for other commercial applications, such as medical applications like the facial plastic reconstruction surgery evaluation.

摘要： A system and method for designing and using freeform reflectors to collect images of a wide angle field-of-view scene is provided. A freeform reflector may enable a wide angle field-of-view to be collected in an unwarped and unwrapped manner such that computer processing may be eliminated. Furthermore, the use of a freeform reflector allows for larger areas of an image sensor chip to be used, thereby providing higher resolution images. Because freeform reflectors may be configured to map a scene onto the image sensor chip in a scalar and mathematically correct manner, output images may be directly displayed from the image sensor chip. Wide angle field-of-view imaging systems, such as surveillance, alarm, and projector system, may utilize freeform reflectors as provided herein.
