摘要： An optical system and method for controlling light propagation along a light path. An optical element such as a lens is formed of a first light transmitting material and has a surface finish effective to scatter light impinging on the surface. Index matching material contacts to a portion of the surface so as to reduce or nullify the scattering effects of the surface finish within the portion. This allows the first optical element to have surfaces that have been generally prepared for scattering light and then later selectively negate the scattering effects of the surface finish by contacting portions of the surface with index matching material. As such, light in the optical element directed toward a surface or boundary within selected portion propagates into or out of the optical element. Light outside of the selected portion is scattered. Such an arrangement helps to reduce image degradation due to light outside of the light path being reflected about within the optical system.

摘要： In an actively illuminated imaging system, illumination of a segmented scene is synchronized with an image sensing period. A scene is segmented into a plurality of scene portions utilizing a segmented lens. In an aspect, a first scene portion is illuminated when an imager is actively collecting photogenerated charge from the first scene portion, and a second scene portion is illuminated when an imager is actively collecting photogenerated charge from the second scene portion. The sensitivity of an image sensor is maximized, while simultaneously minimizing the amount of light that must be supplied to illuminate a scene. An irradiance pattern is varied allowing a more uniform distribution of light. Bands of varying wavelength, polarization, and light intensity may be variously applied to illuminate individual scene segments, as needed to enhance an identification of an object in the scene. The present invention is particularly useful with high frame rate imaging systems.

摘要： An object detection system is provided for detecting a thermal emitting object in a blind zone proximate to a host vehicle. The system includes a thermal radiation detector located on a host vehicle and configured to sense temperature of multiple coverage zones proximate to the host vehicle. A processor processes temperature sensed by an infrared detector. The processor determines a change in thermal temperature sensed by the infrared detector and determines the presence of an object in the coverage zone based on the change in the sensed temperature. An output provides a signal indicative of an object sensed in the coverage zone based on the determined change in temperature. The thermal radiation detector may include a first infrared detector configured to measure temperature of a first coverage zone by receiving infrared radiation from the first coverage zone, and a second infrared detector configured to measure temperature of second and third coverage zones by receiving infrared radiation from the second and third coverage zones.

摘要： A vehicle vision system displays a vehicle pathway image that includes a reticle for visually identifying the in-path portion of the image. A reticle array is disposed between a video camera chip and a lens, and includes a conical or frustro-conical region of substantially un-attenuated light transmissivity surrounded by a region of perceptibly attenuated light transmissivity, such that in-path portions of the displayed image are substantially unchanged and out-of-path portions of the displayed image are perceptibly attenuated. The reticle array may also include a number of reduced transmissivity lines traversing its conical or frustro-conical region to produce a series of receding stadia lines in the in-path portion of the displayed image, enabling the driver to reliably discern the range of displayed objects.

摘要： A near-field radar apparatus includes a fixed beam planar radar antenna and a radiation pattern adaptation device disposed substantially at the near-field boundary of the antenna. The adaptation device comprises a plurality of dielectric elements that individually constitute or approximate different surface portions of an idealized quasi-spherical or quasi-cylindrical radome reflector. The dielectric elements can be maintained physically separate or combined about the diffraction point of the antenna to form a single dielectric element. The dielectric elements may be mounted on a radome that is otherwise transparent to the radiation pattern, or otherwise suspended at or near the near-field boundary of the antenna.

摘要： A vehicle pre-impact sensing system is provided that includes an array of energy signal transmitters mounted on a vehicle for transmitting signals within multiple transmit zones spaced from the vehicle and an array of receiver elements mounted on the vehicle for receiving signals reflected from an object located in one or more multiple receive zones indicative of the object being in certain one or more zones. A processor processes the received reflected signals and determines range, location, speed and direction of the object, determines whether the object is expected to impact the vehicle as a function of the determined range, location, speed and direction of the object, and generates an output signal indicative of a pre-impact event. The system may detect one or more features of a target object, such as a front end of a vehicle. Additionally, the system may modulate the transmit beams. Further, the system may perform a terrain normalization to remove stationary items.
