Multispectral imaging module and portable display device

Abstract

The invention provides a multispectral imaging module and a portable display device, and relates to the technical field of imaging spectrum detection instruments, the multispectral imaging module comprises a primary mirror used for correcting aberration, a micro lens array, an array optical filter and a detector which are sequentially arranged along an optical path, the number of channels of the micro lens array corresponds to the number of channels of the array optical filter to form a plurality of imaging channels, the light beam emitted by the primary mirror sequentially passes through the micro-lens array and the array optical filter, so that light of different wavebands of the light beam is imaged at corresponding positions of the detector through the corresponding imaging channels, and multispectral imaging is achieved. A micro lens array mode is adopted, a data cube of an object can be obtained through one-time collection, spectral imaging of a moving object and an instant phenomenon can be achieved, one-time imaging is achieved, copying imaging of a scene target is achieved, and spectral information of the whole scene target passing through an array optical filter corresponding to the micro lens array is obtained; the device is small in size, low in weight, simple in structure, easy to machine and assemble, economical, convenient and capable of achieving productization.

Description

technical field [0001] The application relates to the technical field of imaging spectrum detection instruments, in particular to a multispectral imaging module and a portable display device. Background technique [0002] Multispectral imaging technology is an emerging technology that organically combines traditional two-dimensional imaging technology and spectral technology to obtain data cubes. [0003] At present, the spectral bands obtained by multispectral imaging technology are few, and the imaging spectrometer made by this method has poor real-time performance, large volume and mass, and cannot realize large field of view and large aperture imaging under the use of light field technology. Therefore, this technology is applied The inability to obtain imaging spectrum information in real time on smartphones has become a pain point in the mobile phone industry. Contents of the invention [0004] The purpose of the embodiment of the present application is to provide a ...
