    Abstract: A color measurement apparatus to which a colorimeter that measures a color of a patch of a color measurement target is configured to be attached includes a support base that supports the color measurement target, a carriage that supports the colorimeter, a scanning mechanism portion that causes the carriage to perform scanning on the support base, and a control portion that controls the scanning mechanism portion, in which the carriage includes a support portion that has an opening portion that exposes a color measurement portion from the carriage in a state in which the colorimeter is supported, and a first measurement portion and a second measurement portion that are provided to interpose the opening portion, and the control portion specifies a position of the patch by measurement results of a measured portion by the first measurement portion and the second measurement portion.

    Abstract: A light detection module has N optical channels, each with an optical filter, a detector, and an amplifier; and an N×1 switch with N input ports each connected to one corresponding output port of each channel to receive an amplified detector output corresponding to a filtered optical intensity incident on that detector. The switch cycles between channels, connecting each amplified detector output in turn to the output port. An ADC samples a time dependent optical intensity signal from the switch, generating a corresponding ADC digital signal output. A microcontroller, connected to the N×1 switch and the ADC, controls acquisition by the ADC to provide a digital voltage data stream from each channel; making the average optical intensity value characterizing the voltage data stream available from each channel at a digital output port of the microcontroller, as N data values, characterizing the light incident on the N channels of the module.

    Abstract: A system for high gain stimulated Raman spectroscopy comprises a first continuous wave laser having an output beam at a tunable optical frequency modulated at a first RF frequency, a second continuous wave laser having a second output beam at an optical frequency modulated at a second RF frequency, wherein the modulation frequencies are selected such that their beat notes represent a Raman resonance frequency, a dual-beam rasterizing probe including first and second photosensors and a rasterizer configured to scan the first and second laser output beams onto a sample, exposing the sample to a reduced average power of laser radiation stimulating the sample to emit Raman radiation signals. The Raman signals are directed to the photosensors and the outputs of the photosensors are supplied to a differential amplifier configured to provide sensitivity and gain to signals at the beat note resonant frequency and to filter signals at other frequencies.
