Abstract
A class of aperture coded spectrometer is optimized for the spectral characterization of diffuse sources. The instrument achieves high throughput and high spatial resolution by replacing the slit of conventional dispersive spectrometers with a spatial filter or mask. A number of masks can be used including Harmonic masks, Legendre masks, and Hadamard masks.
