Embodiment Construction
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] The embodiment of the present invention proposes a spectral restoration technology of a coded aperture spectral imaging device based on prism dispersion, which performs multiple exposures to the target for a two-dimensional coded template similar to the Hadada code transformation function form, and a prism modulates the coded template. Inverting and decoding the optical imaging after the dispersion of the light field, changing the limitation ...
