The invention discloses a high-resolution large-field-of-view imaging method. The method comprises the following steps: step 1, designing a high-resolution large-field-of-view calculation imaging optical system; 2, imaging a target scene by using a high-resolution large-view-field calculation imaging optical system to obtain a target scene image; and 3, performing image restoration on the target scenery image by using an image restoration algorithm to obtain a high-resolution large-field-of-view image. The problems that an existing high-resolution large-view-field imaging system is complex in design, large in size and weight and high in cost are solved, the size, the weight and the cost of a hardware part are reduced, and the designed high-resolution large-view-field imaging system is more suitable for a high-resolution large-view-field space optical imaging system with strict requirements for the weight and the size.
Description
technical field [0001] The invention belongs to the technical field of high-resolution large-field-of-view space optical imaging systems, and in particular relates to a high-resolution large-field-of-view imaging method. Background technique [0002] High-resolution imaging systems generally have a large aperture, and it is difficult to obtain better image quality in the peripheral field of view of a large-aperture imaging system. In order to solve the problem of high resolution and large aperture caused by traditional design methods, commonly used methods include: multi-aperture imaging system, complete machine or scanning mirror swing, and off-axis reflective optical system with free-form surface . These methods can effectively achieve high resolution and large field of view simultaneously. However, the space optical imaging system has limitations such as weight and volume stability. The above-mentioned methods will increase the difficulty of designing and adjusting the ...
