Embodiment Construction
[0037] The specific implementation steps of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] like figure 1 As shown in the flow chart, the low-order aberration correction method for telescopes based on deep learning is mainly divided into two parts. figure 1 The left part is the preparatory work of the telescope aberration correction system, that is, the training process of the weight parameters of the neural network model, and the right part is the aberration correction process of the actual system, which includes the following steps:
[0039] Step 1 Establish the optical system model:
[0040] In the optical simulation software Zemax, the optical system model of the off-axis reflecting telescope system to be installed is established according to the structural parameters;
[0041] Step 2 Acquisition of neural network data set (including training set and test set):
[0042] After the off-axis reflective optical s...
