Abstract: A polarization image sensor includes: photodiodes arranged on an image capturing plane; a color mosaic filter in which color filters in multiple different colors are arranged to face the photodiodes; an optical low-pass filter which covers the color mosaic filter; and polarization optical elements located closer to a light source than the optical low-pass filter is. Each polarization optical element covers an associated one of the photodiodes and makes light which is polarized in a predetermined direction in a plane that is parallel to the image capturing plane incident onto the optical low-pass filter. The color filters are arranged so that light that has passed through polarization optical elements is transmitted through an associated one of the color filters in a single color. Each color filter covers multiple photodiodes.

Abstract: An imager contains an image sensor with laterally varying spectral response. The imager is scanned over a scene or object to form a spectral image. The spectral responses are repeated at different positions in the field of view so as to reduce the effect of scene nonidealities, such as angle dependence or temporal variation, on the spectral image data. A part of the image sensor may be used for conventional two-dimensional imaging. This part of the image sensor may be used to estimate the scene geometry and scan movement, enabling further improvement in the spectral integrity.

Abstract: An imaging system having a solid-state auto focusing system advantageously images broadband light reflected from an object to be imaged using a lens objective having chromatic aberration, which focuses different colors of light at different focal planes. Using the color information in the focal planes in conjunction with an object distance determined by a range finder, a luminance plane is constructed that has a focused image of the object. The system provides the focused image of the object without the use of any moving parts.

Abstract: Disclosed examples of optical systems having a plurality of light sources with each source having a different spectral outputs may be calibrated by measuring a spectral characteristic of the combined light with two measurements, e.g., one from a colorimeter and one from a sensor included in the system. Accordingly, one can determine a transform function in response to the two measures that models a feedback response of the optical system for each of a plurality of the inputs that would cause the optical system to generate radiant energy within a predetermined range of a spectrum. In order to calibrate the optical system, the transform function is programmed in the optical system to enable the optical system to transform an input to the optical system to a plurality of unique control signals each for controlling a respective light source of the plurality of light sources.
