基于波前编码的变F数光学系统景深扩展设计
Depth-of-Field Extension Design of Optical Systems with Variable F-Numbers Based on Wavefront Coding
摘要
Abstract
Existing wavefront coding methods require the design of corresponding phase masks for optical systems with variable F-numbers,which increases the design complexity and cost.To ad-dress this issue,this paper proposes a multi-structure wavefront coding optimization design scheme that,in conjunction with an efficient optimization algorithm,achieves unified optimization of phase mask parameters for different F-number optical systems using a single phase mask.This design significantly reduces the manufacturing cost of the phase plate and simplifies the system's complexity.Experimental results show that the proposed scheme,using a single phase plate,can achieve good defocus consistency in the modulation transfer function for optical systems with dif-ferent F-numbers(F=1.4,1.6 and 1.8),extending the depth of focus of traditional infrared sys-tems by a factor of 3 to 5.关键词
