Lenslet array based integral field spectrograph and data processing

A lenslet based integral field spectrograph (IFS) may have a design that makes better use of the detector pixels by placing adjacent spectra next to each other rather than staggering the spectra. Such a design maintains the main compactness and simplicity of prior lenslet array based IFSs, but improves the detector efficiency, which is rather low in conventional lenslet array based IFSs.
