Abstract: Technologies are generally described for determination of a spectral profile of a sample. A microscope with spectroscopic capability may include a multitude of light sources, one or more photo detectors, and an analysis module. The microscope may be a table-top microscope or a hand-held microscope. The light sources may be configured to illuminate at least one portion of the sample, the photo detectors may be configured to detect returned light from the sample in response to the illumination, and the analysis module may be configured to analyze the detected light to determine a spectral profile of the sample. In some examples, the spectral profile of the sample may be compared to a spectral profile of a reference sample to evaluate the sample, where the sample may be evaluated to determine an identity, a quality, an authenticity, a composition, a density, a reflectivity, and/or an amount of the sample.

A microscope with spectroscopic capability may include a multitude of light sources, one or more photo detectors, and an analysis module. The microscope may be a table-top microscope or a hand-held microscope, for example. The light sources may be configured to illuminate at least one portion of the sample, the photo detectors may be configured to detect returned light from the sample in response to the illumination, and the analysis module may be configured to analyze the detected light to determine a spectral profile of the sample. In some examples, the spectral profile of the sample may be compared to a spectral profile of a reference sample to evaluate the sample, where the sample may be evaluated to determine an identity, a quality, an authenticity, a composition, a density, a reflectivity, and/or an amount of the sample.

Abstract: A method and apparatus for employing a light shield to modulate pixel color responsivity. The improved pixel includes a substrate having a photodiode with a light receiving area. A color filter array material of a first color is disposed above the substrate. The pixel has a first relative responsivity. A light shield is disposed above the substrate to modulate the pixel color responsivity. The light shield forms an aperture whose area is substantially equal to the light receiving area adjusted by a reduction factor. The reduction factor is the result of an arithmetic operation between the first relative responsivity and a second relative responsivity, associated with a second pixel of a second color.

Abstract: An imaging system using a color shutter receives signals indicative of color information in a plurality of planes together with infrared information and a signal indicative of the infrared radiation alone. The infrared radiation signal may be subtracted from the signals associated with the color planes to develop signals free of infrared radiation effects for each of the desired color planes. In addition an infrared signal is available which may have useful applications in some situations. In this way, color information color bands may be obtained without the need an infrared filter and infrared information is retained for use in other applications if desired. In addition infrared and dark current information may be derived that can be used for dark current correction.
