Spectral imaging analysis system and imaging analysis method thereof

Abstract

The invention provides a spectral imaging analysis system and an imaging analysis method thereof. The spectral imaging analysis system comprises an imaging lens array, a light calculation chip and animage sensor, wherein the imaging lens array acquires an original image of a to-be-detected target; the light calculation chip comprises a polarizer, a liquid crystal phase delayer array and a polarization analyzer; the light calculation chip is subjected to polarization treatment by the polarizer and then subjected to interference treatment by the liquid crystal phase delayer array to obtain an incident spectrum and generate a group of fundamental frequency and harmonic waves; the liquid crystal phase delayer array constructs a spectrum regression function of the incident spectrum according to the fundamental frequency and the harmonic waves; polarization interference state information of the incident spectrum is detected by the polarization analyzer; the image sensor generates a group ofspectrum image sequences containing space information and the polarization interference state information; and physical and chemical quantity information of a substance of the incident spectrum is calculated according to the spectrum regression function. Compared with the prior art, the spectral imaging analysis system and the imaging analysis method thereof have the advantage that real-time full-spectrum imaging and spectral analysis of a dynamic target are realized.
