Abstract: A method, a system, and a non-transitory computer readable medium for accurate Raman spectroscopy. The method may include executing at least one iteration of the steps of: (i) performing, by an optical measurement system, a calibration process that comprises (a) finding a misalignment between a region of interest defined by a spatial filter, and an impinging beam of radiation that is emitted from an illuminated area of a sample, the impinging beam impinges on the spatial filter; and (b) determining a compensating path of propagation of the impinging beam that compensates the misalignment; and (ii) performing a measurement process, while the optical measurement system is configured to provide the compensating path of propagation of the impinging beam, to provide one or more Raman spectra.

Abstract: Disclosed is an optical system for imaging, which enables high resolution. An optical system for imaging, which focuses inspection light and monitoring light on an inspection target, includes a dioptric group configured to receive inspection light and monitoring light and to primarily focus the inspection light and the monitoring light on different locations, and a reflection dioptric group configured to reflect and refract the inspection light and the monitoring light that have passed through the dioptric group and to bring the inspection light and the monitoring light into one focus.

Abstract: An optical system (230) comprises an image sensor (231), a reference sensor (232), and an optical multiplexer (300). The optical multiplexer defines a first area for receiving a first portion of incoming light and a second area (320) for receiving a second portion of the incoming light. The second area radially surrounds the first area. The optical multiplexer is arranged to direct the first portion of the incoming light to the image sensor (231) and the second portion of the incoming light to the reference sensor (232). The optical multiplexer may take the form of a pinhole minor (300).

Abstract: A spectroscopy analyzer for the identification of substances contained in a sample using a set of spectroscopy techniques and methods using a single device that can be configured to conduct a variety of tests using multiple optical devices and elements. The results are combined in a consolidated sample diagnostic profile that can then be compared with benchmark information produced from other spectroscopy analysis results downloaded from external databases and interpreted using artificial intelligence.

Abstract: Disclosed is a method of processing a Raman spectroscopy signal. The method includes: obtaining a first resolution of Raman spectroscopy by irradiating a target sample with broadband excitation light; calculating a Raman spectroscopy signal corresponding to the Raman spectroscopy of the first resolution; and calculating a signal corresponding to a second resolution of Raman spectroscopy that is higher than the first resolution by deconvoluting a Raman light signal.

Abstract: The present disclosure provides a portable apparatus for detecting early crop diseases based on spatial frequency domain imaging. The apparatus includes an end cover, a spatial frequency domain imaging apparatus, a dark box body, a telescopic section, and an opening-and-closing apparatus connected in sequence. The detection method includes: putting a crop sample to be detected into the dark box body from a bottom; projecting structured light of sine grey scale patterns with different spatial frequencies to the crop sample; after the sine gray scale pattern is switched each time, acquiring, by a camera, a diffuse reflection image of a surface of the crop sample once; after capturing all diffuse reflection images, performing uniformity correction on the images, demodulating the images, and extracting an alternating current component; and inputting an alternating current component image to a trained disease detection model, and determining whether the crop sample has a disease.
