Multispectral imaging module and portable display device

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, o
