The infrared optical instrument is disposed on an ATR prism side of a sample, and is provided to irradiate the ATR prism with an infrared light, and collect the infrared light from the ATR prism. The Raman module is disposed on a side opposite to the ATR prism side relative to the sample, and has a guide tube that outputs an excitation light from an excitation light source to the sample, and a lens portion disposed inside thereof. An end of the guide tube is in a position to push the sample to the ATR prism. The Raman module has a lens position adjustment mechanism that moves the lens portion along an optical axis, and a spectroscope that detects a Raman scattering light collected by the lens portion.

According to an aspect of the invention, a system includes an excitation light source; an objective that is configured to image excitation light onto the sample, such that the excitation light causes the sample to emit fluorescence light; a channel separator that is configured to separate the fluorescence light into a plurality of spatially dispersed spectral channels; and a sensor. The excitation light source includes a light source and a plurality of lenslet arrays. Each of the lenslet arrays is configured to receive light from the light source and to generate a pattern of light, and the patterns of light generated by the lenslet arrays are combined to form the excitation light. The objective is configured to simultaneously image each of the patterns of light to form a plurality of parallel lines or an array of circular spots at different depths of the sample.

Abstract: An object is to quantify the texture such as irregularity and gloss of a metal surface. Centers of Lab chromaticity distributions are identified (S145), and one of the Lab chromaticity distribution is entirely shifted (mapped) by deviations ΔA, ΔB and ΔL of a central coordinate, such that one of central coordinates of two distributions U1(L,a,b) and U2(L,a,b) matches with the other central coordinate (S146). A texture spread index that indicates a difference in spatial spread is then computed (S147). This configuration computes the spatial spread of the Lab chromaticity distribution in a three-dimensional space, and quantifies the irregularity of an inspection plane by diffraction phenomenon of illumination light. The difference in spread other than the color is applicable to evaluation of the irregularity of the metal surface or the like.

Abstract: Aspects are generally directed to multi-sensor boresight alignment methods and systems for a multi-spectral reimaging optical system. In one example, a multi-sensor boresight alignment system includes a system interface to receive a first image frame from a first sensor and a second image frame from a second sensor, the first image frame having a contrast within a first spectral band and including a first image of a plate having a pattern of apertures, and the second image frame having a contrast within a second spectral band and including a second image of the plate. The system includes a field programmable gate array (FPGA) coupled to the system interface, the FPGA configured to spot track each image frame to identify a corresponding centroid of the pattern of apertures and correct an optical alignment between the first and second sensors based on a position of the corresponding centroids.
