Abstract: The present application provides a terahertz spectral imaging data reconstruction method, an apparatus, a device, and a storage medium. The method includes: scanning a target object according to the first spatial interval and the first time domain sampling period to acquire the first terahertz spectral data; scanning the target object according to the second spatial interval and the second time domain sampling period to acquire the second terahertz spectral data, the first spatial interval is larger than the second spatial interval, and the first time domain sampling period is larger than the second time domain sampling period; and reconstructing the second terahertz spectral data on basis of the first terahertz spectral data by using the preset reconstruction method to obtain the third terahertz spectral data.

Abstract: A method for collecting and processing terahertz spectral imaging data includes: scanning an object to generate terahertz spectral data having a hyper- or low-spectral resolution respectively at a plurality of pixel points; collecting the terahertz spectral data and recording coordinate data of each pixel point, thereby obtaining a mixed data including a hyper-spectral data and a low-spectral data corresponding to different pixel points; constructing a hyper-spatial and low-spectral imaging data-cube from the mixed data; extracting a hyper-spectral data-set from the mixed data; and reconstructing a hyper-spatial and hyper-spectral imaging data-cube from the hyper-spatial and low-spectral imaging data-cube based on the hyper-spectral data-set. A terahertz spectral imaging apparatus is further provided.
