摘      要：Hyperspectral imaging(HSI)is a powerful tool widely used for various scientific and industrial applications due to its ability to provide rich spatiospectral ***,in exchange for multiplex spectral information,its image acquisition rate is lower than that of conventional imaging,with up to a few *** particular,HSI in the infrared region and using nonlinear optical processes is impractically slow because the three-dimensional(3D)data cube must be scanned in a point-by-point *** this study,we demonstrate a framework to improve the spectral image acquisition rate of HSI by integrating time-domain HSI and compressed ***,we simulated broadband coherent Raman imaging at a record high frame rate of 25 frames per second(fps)with 100 pixels×100 pixels,which is 10×faster than that of previous work,based on an experimentally feasible sampling scheme utilizing 3D Lissajous scanning.
