Abstract: A computer-implemented system and method for detecting vehicle occupancy is provided. Light beam pulses emitted from a lidar system are applied to a passing vehicle. Scans of an object are generated from the light beam pulses. A signal is received from each of the beam pulses reflected at a point of reflection along a segment of the vehicle. A time is measured from when each beam pulse was emitted to receipt of the signal. A distance of the signal from the lidar system is calculated using the measured time. The points of reflection for that vehicle segment are positioned in relation to one another as a scan. The scans are compiled in a consecutive order according to the vehicle and a three-dimensional image of an interior of the vehicle is generated from the consecutive scans. A presence or absence of vehicle occupancy is determined based on the three-dimensional image.

Abstract: A mirror array is positioned in relationship to a high intensity power light source to receive at least a portion of a high intensity light beam and to reflect at least a portion of the high intensity light beam. An aperture plate is positioned between the high intensity power light source and the mirror array. The aperture plate has an open area and an opaque area, the open area including a main portion and a tab portion. The main portion is located on a side of the tab portion distal from an incident light direction of the received high intensity beam of light. The open area is sized and positioned to allow rays of the high intensity beam of light to be passed through the tab portion and reflections of the passed rays of the high intensity beam of light to exit through the main portion.

Abstract: A laser line generator system that utilizes a light guide element to convert high energy coherent light generated by a high fill-factor laser diode bar into homogenous light, and utilizes one or more slow-axis relay lenses to image the homogenous light such that it forms a homogenous line illumination pattern on an illumination plane. The light guide utilizes parallel or down-tapered side walls to mix received coherent light in the slow-axis direction by way of total internal reflection. A Keplerian telescope including two cylinder lenses is optionally used in place of the slow-axis relay lens. Optional fast-axis lenses are used to assist in focusing the homogenous light at the illumination plane. The laser light generator forms, e.g., a single-pass imaging system for a scanning/printing apparatus in which the homogenous line illumination pattern is directed onto a linearly arranged series of spatial light modulators, such as Digital Micromirror Devices (DMDs).

Abstract: A linear concentrating solar collector includes two trough-type reflectors having respective curved reflective surfaces that define respective focal lines, and are connected along a common edge in a decentered arrangement such that the focal lines are parallel and spaced-apart, and such that solar radiation reflected by the curved reflective surfaces is concentrated and overlaps in a defocused state. A solar cell is disposed in the overlap region to receive the all of the reflected radiation from the curved reflective surfaces in a defocused state. An optional solid optical structure is used to support and position the trough-type reflectors and solar cell, and to facilitate self-forming of the curved reflective surfaces.

Abstract: An optical imager system and method of operating the optical imager system, can include one or more imager modules including a laser light source, a collimator, an illumination optical system, a grating light valve, a spatial light modulator and a projection optical system. A group of imager modules can include the one or more imager modules. The group of imager modules is operable in a stacked arrangement to produce an image from in-line stitching of individual images generated by the one or more imager modules. The illumination optical system can homogenize, shape, and direct a beam from the laser light source onto the grating light valve, and homogenization can occur in a cross-process direction.
