Abstract
An optical computing chip includes a light source array, a first concave mirror, and a modulator array. The light source array is located on an objective focal plane of the first concave mirror. The modulator array is located on an image focal plane of the first concave mirror. The light source array generates a first optical signal based on first data. The first concave mirror outputs a first reflected optical signal based on the first optical signal. The modulator array receives the first reflected optical signal, obtains first spectrum plane distribution data based on the first reflected optical signal, and modulates the first spectrum plane distribution data onto the modulator array.
