Query: Compressive fluorescence spectral imaging with a spectrometer   We present an efficient approach and principle experiment for compressive
sensing (CS) fluorescence spectral imaging. According to the dimension-reduced
effect of CS, the spectral and spatial information was simultaneously obtained
by using a fiber spectrometer without mechanical scanning. As a method
verification, we demonstrated spectral imaging under only two typical
wavelengths, but the spectral resolution is up to 1.4nm depended on the fiber
spectrometer. The method could obtain 50% light energy from the object, much
larger compared with mechanical scanning which detects light of only one point
per measurement. The relationship between sampling rate and image quality is
also discussed in this study.
