Problems solved by technology

[0002] In the related art, each spectral detection device can usually only be used to detect a specific band. If it is necessary to realize multi-band spectral detection, for example, to realize multi-band spectral detection from ultraviolet light to infrared light, you need to purchase the corresponding All spectral detection devices, therefore, the cost of realizing multi-band spectral detection is high

Abstract

The present disclosure relates to an optical device, comprising: a detector; an optical component for receiving a light beam from a light source or a target scene; a changing component comprising a plurality of semiconductor nanocrystals with corresponding spectral transmittances and correspondingly configured A plurality of rotatable micromirrors, wherein the optical component injects the light beams to the plurality of semiconductor nanocrystals, and the plurality of semiconductor nanocrystals transmit the light beams from the optical component to the plurality of micromirrors. mirrors; and a control component, used to control the rotation of the plurality of micromirrors, so that the plurality of micromirrors will incident the light beams from the plurality of semiconductor nanocrystals to the detector. Therefore, not only more wavelength bands and / or customizable spectral detection can be realized more flexibly, but also the volume of the optical device can be reduced.

Description

technical field [0001] The disclosure relates to the technical field of spectrum detection and spectrum imaging, and in particular to an optical device. Background technique [0002] In the related art, each spectral detection device can usually only be used to detect a specific band. If it is necessary to realize multi-band spectral detection, for example, to realize multi-band spectral detection from ultraviolet light to infrared light, you need to purchase the corresponding All spectral detection devices, therefore, the cost of realizing multi-band spectral detection is high. Contents of the invention [0003] In view of this, the present disclosure proposes an optical device. [0004] According to an aspect of the present disclosure, an optical device is provided, comprising: [0005] detector; [0006] an optical assembly for receiving a light beam from a light source or a target scene; [0007] a changing component comprising a plurality of semiconductor nanocrys...
