Abstract: A method characterizes a scanning light source configured to emit illumination propagating in any one of a plurality of directions spanning an angular range. The method includes (i) detecting, with a camera, illumination propagating at each of the plurality of directions; (ii) storing image data corresponding to a response of the camera to the detected illumination. The method also includes (iii) processing the image data to characterize at least one of the angular range, pointing accuracy, pointing jitter, a divergence of the illumination, a uniformity of the illumination, and a fidelity of a scanning pattern, formed by the scanning light source, to a predetermined pattern.

Abstract: A monolithic polarizing diffractive structure includes a system having at least two parallel continuous planar surfaces, a diffractive pattern on one of the at least two parallel continuous surfaces, the diffractive pattern including at least two diffractive elements integral with the one of the at least two continuous surfaces, the at least two diffractive elements defining a monolithic diffractive pattern, and a polarizing pattern on one of the at least two parallel continuous surfaces.

Abstract: A monolithic polarization controlled angle diffuser includes a system having a first surface and a second surface, a controlled angle diffuser pattern for providing an angular distribution at an illumination plane, the controlled angle diffuser pattern being on one of the first and second surfaces of the substrate, and a polarizing pattern on one of the first and second surfaces of the substrate. The controlled angle diffuser pattern includes at least two controlled angle diffuser elements. Each controlled angle diffuser element outputs different angular distributions. The polarizing pattern includes at least two polarizing elements. Each polarizing element corresponds to a respective controlled angle diffuser element. The at least two polarizing elements output polarizations are rotated with respect to one another.
