Abstract: A method and apparatus for obtaining reference samples during the generation of a mid-infrared (MW) image without requiring that the sample being imaged be removed is disclosed. A tunable MIR laser generates a light beam that is focused onto a specimen on a specimen stage that moves the specimen in a first direction. An optical assembly includes a scanning assembly having a focusing lens and a mirror that moves in a second direction, different from the first direction, relative to the stage such that the focusing lens maintains a fixed distance between the focusing lens and the specimen stage. A light detector measures an intensity of light leaving the point on the specimen. A controller forms an image from the measured intensity. A reference stage is positioned such that the mirror moves over the reference stage in response to a command so that the controller can also make a reference measurement.

Abstract: This invention relates to a system and method to improve the signal to noise ratio (SNR) of optical spectrometers that are limited by nonrandom or fixed pattern noise. A signal from a sample is collected using a short test exposure, a total observation time to maximize SNR is calculated, and the total observation time is achieved by averaging multiple exposures whose time is selected based on the time dependent noise structure of the detector. Moreover, with a priori knowledge of the time dependent noise structure of the spectrometer, this method is easily automatable and can maximize SNR for a spectrum of an unknown compound without any user input.

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.
