Embodiment Construction
[0045] The invention relates to a complete set of large focal depth imaging system based on wavefront coding mechanism and a super-resolution processing method based on single image enlargement for the wavefront coding imaging system.
[0046] The invention provides a wavefront encoding imaging system, comprising a wavefront encoding imaging lens, a 1 / 3 inch image detector and a decoding processing unit, the wavefront encoding imaging lens comprising a first lens ( figure 1 In the lens 1), the phase mask plate, the second lens ( figure 1 lens 2) and the third lens ( figure 1 The lens 3) in the lens; the first lens, the phase mask plate, the second lens, the third lens, the 1 / 3 inch image detector and the decoding processing unit are sequentially arranged on the same optical path;
[0047] The radius of curvature of the front surface of the first lens is 18.9670mm, the semi-aperture of the X direction and the semi-aperture of the Y direction of the front surface of the first l...
