Embodiment Construction
[0019] Such as figure 1 As shown, the large field of view optical imaging system based on the computational imaging technology of the present invention includes a common primary mirror, a microlens array and a detector array. The shared primary mirror is a monocentric spherical mirror, which is composed of two hemispherical mirrors, and the aperture is located in the middle of the two hemispherical mirrors. Such as Figure 2a shown. The light rays of different fields of view enter the common primary mirror from the object side of the optical system, and the common primary mirror performs an imaging; a microlens array corresponding to the detector array is introduced behind the primary image surface of the common primary mirror, and each microlens on the microlens array is exactly the same , the light emitted from the primary image plane is imaged twice by the microlens array, then arrives at the detector array and is finally imaged; the detectors on the detector array are al...
