Light field spectrum microscopic imaging method and light field spectrum microscopic imaging system based on microlens array

The invention provides a light field spectrum microscopic imaging method of combining a microlens array, a microscopic objective, and a spectrum beam splitting system, and a light field spectrum microscopic imaging system. Light field and spectrum five-dimensional vector information of an object are acquired in an integration time, and the preposed objective of the imaging system adopts the microscopic objective, and then convenience is provided for detection of components of small substances. The microlens array is disposed on the image plane position of the microscopic objective, and the front-end microscopic objective and the microlens array are used to form the light field microscopic imaging system, and the image plane of the microlens array is used to acquire four-dimensional light field information of a sample. The light field information is recorded by the microlens array, and is transmitted to a detector plane by the beam splitting system at the same time, and the light field spectrum microscopic ima
