Optical modulation micro-nano structure, micro-integrated spectrometer and spectrum modulation method

Abstract

An optical modulation micro-nano structure, a micro-integrated spectrometer and a spectrum modulation method are provided. The optical modulation micro-nano structure includes an optical modulation layer located on a photoelectric detection layer that can modulate incident light to form differential responses on the photoelectric detection layer, so as to obtain an original spectrum by reconstruction, thereby overcoming the defects that the existing spectrometers rely too much on precise optical components, which makes spectrometers bulky, heavy and expensive. The optical modulation layer includes a base plate and at least one modulation unit; the base plate is provided on the photoelectric detection layer, and each of the modulation units is located on the base plate; each modulation unit is provided with several modulation holes penetrating into the base plate, and respective modulation holes inside a same modulation unit are arranged into a two-dimensional graphic structure with a specific pattern.
