Abstract: A method and an apparatus for camera-free light field imaging with optoelectronic intelligent computing are provided. The method includes: obtaining an optical computing result by an optical computing module in response to receiving a light signal of an object to be imaged, in which the optical computing result includes light field imaging of the object to be imaged; computing by an electronic computing module the optical computing result to obtain an electronic computing result; and in response to determining based on the electronic computing result that cascading is required, forming a cascade structure by taking the electronic computing result at a previous level as an input of the optical computing module at a current level, and in response to determining that cascading is not required, outputting a final result.
