CALCULATION OF A CURVOLINEAR PHOTOSENSITIVE SURFACE OF THE RECEIVER, MATCHED WITH A NORMAL LENS

Annotation

The purpose of the work is to solve the problem of studying and calculating the parameters of a curved photosensitive surface of the receiver, consistent with a normal lens. Normal lenses it is lenses with a certain image field of medium size. An option has been proposed for the implementation of a photosensitive surface of a curved receiver for a normal lens. Lens lenses with different image surface shapes are analyzed. Using the least squares method, we obtained an equation for the approximating function of the curve corresponding to the shape of the image surface of the selected lens. Using the developed diagrams of object deformation, the strength characteristics of the photosensitive surface of a curved receiver were assessed. Compared with the flat form, the new form of the photosensitive surface expands the range of achieving the best image quality in an optical-electronic device. The curved photosensitive surface of the receiver makes it possible to reduce the influence of field curvature aberration in the selected lens and reduce the size of scattering spots at the edge of the field by half. The results of numerical modeling will find their application in the design of technology for manufacturing a curved photosensitive surface, as well as when agreeing on the permissible values of deviations that appear during the development process. The sequence of calculating the parameters of the curved photosensitive surface of the receiver can be used in the design of optical systems and receiving modules. The proposed method allows us to simplify the solution to the problem of creating an image on the photosensitive surface of the receiver and reduce the influence of field curvature without the use of lens compensators.
