Abstract: An apparatus and a camera system are provided. The apparatus includes an imaging screen configured to diffuse incoming light, and a lens system coupled to the imaging screen and configured to focus light from the imaging screen onto a CMOS image sensor. The imaging screen includes a ceramic diffuser layer fused into a surface of a glass substrate, and a thickness of the ceramic diffuser layer is within a range of about 7-10 μm.

Abstract: An optical circuit switch including a two-dimensional fiber collimator includes a hole plate to hold and align a plurality of optical fibers. Fiber pathways within the hole plate can be formed using a femtosecond laser irradiation chemical etching (FLICE) technique. The use of the FLICE technique allows for extremely precise channels to be formed which allows for fibers to be aligned more closely with their intended alignment. The technique also allows for the channels or fiber pathways to be formed in a thicker material, which allows for greater structural support and robustness of the fiber collimator in use.
