Change the liquid crystal lens from a positive lens state to a negative lens state

state, collect each frame of interference fringe image in the process of change, and perform wavefront phase fitting on the image to obtain the liquid crystal lens in the

The Power value corresponding to each frame during the change process. When the liquid crystal lens Power=3.0l / m, the position of the focal object plane (the focal plane

The distance from the lens group) is about 12.6cm; when the liquid crystal lens Power=‑4.4l / m, the position of the focused object surface is 234cm.

In the foregoing example, the dynamic change process of the liquid crystal lens is that the voltage value loaded on the liquid crystal lens is changed by the first voltage

The process of changing the liquid crystal lens from the positive lens state to the negative lens state after the value is switched to the second voltage value, the acquisition time is

The moment when the voltage value loaded on ...

Description

Panoramic deep image acquisition method, synthesis method, device, equipment and storage medium technical field The present invention relates to the technical field of optical imaging, especially a kind of panoramic deep image acquisition method, synthesis method, device devices, devices and storage media. Background technique [0002] Panoramic depth of field (Extended Depth of Field, EDOF) optical imaging system can obtain more abundant objects Information. In order to break through the depth-of-field limitation of traditional optical imaging systems, researchers have proposed many methods to achieve enlarged optical The depth of field of the system. Among them, the methods of expanding the depth of field can be mainly divided into three categories: the first category is achieved by reducing the numerical aperture of the system Depth of field extension; the second method is Wavefront coding (WFC), by performing phase modulation at the pupil position The coded ima...
