Abstract
Disclosed is a short-wave infrared spectrum detector, including: a photosensitive chip, including a plurality of detection pixels; a substrate; and a wavelength division component array, including a plurality of wavelength division pixels, each of the plurality of wavelength division pixels corresponding to a narrowband transmission spectrum, wherein the photosensitive chip and the wavelength division component array are monolithically integrated on both sides of the substrate, and an orthographic projection of each of the plurality of wavelength division pixels on the substrate covers an orthographic projection of at least one detection pixel on the substrate. The wavelength division structure and the photosensitive chip are integrated, so that each pixel has the ability of frequency-selective light spectrum detection, and a short-wave infrared spectrum detector integrated with wavelength division and detection is formed, realizing the miniaturization of the short-wave infrared spectral detection system.
