AI Technical Summary
Traditional imaging spectrometers are difficult to monitor a region in real time and suffer from problems such as low spectral brightness, low signal-to-noise ratio, contradiction between field of view and spectral range, severe stray light, and limitations of advanced spectral parameters.
A regional spectral monitoring system based on prism dispersion is adopted, including a front optical structure, a rear optical structure, a detection and photoelectric conversion module, an image and spectral data processing module, and a phenomenon inference and output module. By setting a field stop and an aperture stop on the intermediate image plane, the imaging optical path and the dispersive optical path are separated. A CMOS detector is used for photoelectric conversion, and image data is processed to extract brightness and spectral changes.
It enables real-time monitoring of brightness and spectral changes within a region, improves the signal-to-noise ratio, expands the spectral band range, and enhances system stability and real-time performance, making it suitable for fields such as chemical engineering, battery energy storage, and airport security.
