基于波前编码的大景深成像技术

In this paper，the depth of field of optical imaging system can be extend if a wave front coding plate was put into the imaging system and using imaging processing technology to recover the middle blurred image. This method can keep the aperture size and better image quality was obtained. Firstly, several methods used for extend the depth of field were presented. Then the wave front parameters were obtained using the invariant property of optical character function and stabilized imaging method. The simulation result shows the wave front plate can be used for extend the depth of field.
