    Abstract: A multi-slit type spectrometer includes a light diffracter which diffracts an incident light according to wavelengths; an optical shutter array member including a plurality of optical shutter elements arranged in correspondence with wavelength bands diffracted by the light diffracter, operable to transmit an incident ray according to an applied voltage, and made of PLZT. A zone of a given number of adjacent optical shutter elements is applied with a voltage corresponding to the wavelength bands of the rays incident upon the zone of adjacent optical shutter elements at a specified timing so that the rays respectively pass through or are reflected at the optical shutter elements. A signal processor receives the ray which has passed through or has been reflected at each optical shutter element and outputs an electrical signal according to the intensity of the received ray. A calculator calculates the intensity of the incident ray for each wavelength band in accordance with the electrical signal output from the signal processor and the specified applying timing.

    Abstract: In a Raman microscope, a depth measurement processor performs depth measurement by changing a focal position of laser light along a depth direction of a sample which is an irradiation direction of the laser light with respect to the sample, and meanwhile, acquiring a Raman spectrum of the sample at a plurality of points in the depth direction. A display processor displays an input screen used to input a parameter at a time of performing the depth measurement on the sample in association with a surface image of the sample on a stage. The parameter includes a range in which the focal position of the laser light is changed along the depth direction and an interval between the plurality of points within the range.

    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.
