Embodiment 1
[0074] Embodiment 1: measuring method of the present invention comprises the steps:
[0075] Step 1, design the convolution template H corresponding to the coding aperture.
[0076] When the optical signal passes through the linear invariant system, the output optical signal X out Can be regarded as the input optical signal X in Convolution result with convolution template H, ie F out =F in *H, where the convolution template H is only related to the imaging system. In this imaging system, the convolution template H is determined by the coded aperture template P in the system. The specific steps are as follows:
[0077] 1.1) In order to obtain a better coding effect, the size of the convolution template matrix H is determined by the resolution of the desired high-resolution image. When the resolution of the high-resolution image is n×n, the convolution template matrix H The size of is set to n×n dimensions, and the encoding effect at this time is the best;
[0078] 1.2) Co...
Embodiment 2
[0110] Embodiment 2: measuring method of the present invention comprises the steps:
[0111] Step A, design the convolution template H corresponding to the coding aperture.
[0112] When the optical signal passes through the linear invariant system, the output optical signal X out Can be regarded as the input optical signal X in Convolution result with convolution template H, ie F out =F in *H, where the convolution template H is only related to the imaging system. In this imaging system, the convolution template H is determined by the coded aperture template P in the system. The specific steps are as follows:
[0113] A1) In order to obtain a better coding effect, the size of the convolution template matrix H is determined by the resolution of the desired high-resolution image. When the resolution of the high-resolution image is n×n, the convolution template matrix H The size of is set to n×n dimensions, and the encoding effect at this time is the best;
[0114] A2) Conv...
