摘要
波前编码系统是一种新型的光学数字混合成像系统。利用光阑处放置优化设计的三次相位板对波前的调制作用,可以实现在像面附近相当范围内系统的点扩展函数一致;进一步通过数字图像去卷积算法可以得到相当景深范围内清晰的成像,从而实现景深延拓。根据传统显微系统的特点,提出了一种基于传统显微物镜系统的波前编码显微系统设计思路,设计并加工了一套10×,40×波前编码显微成像系统。基于传统显微系统的波前编码显微系统可以有效地延拓传统显微物镜系统的景深,提高系统的成像质量。
Wavefront coding is a new imaging system based on optical digital mixed techonology. By using the modulating action of the cubic phase mask on the stop, the point spread functions （PSFs） of the system in a certain scope nearby the image surface will be the same; then the sharp image will be acquired by using the image deconvolution algorithm in a certain depth range of the field of the system to extend the depth of field. A novel design method of wavefront coding microscope on the basis of the traditional microscope is proposed. The 10 ×, 40 × wavefront coding microscope system is designed and manufactured. The wavefront coding microscope system based on the traditional microscope system can extend the depth of field and improve the imaging quality effectively.
