摘要

开展了用相位差异散斑技术实现图像采集和图像恢复的实验

在实验室环境下设计了针对扩展目标的相位差异散斑成像双相机实验平台。用两台外触发模式的相机同步采集焦面和指定离焦面上的短曝光图像

用变形镜构造光学系统误差

用强力热吹风机模拟大气湍流。分析了用多台相机与单台相机相比引入的不同问题

给出了多通道之间相面旋转问题的处理方法和多通道之间读出噪声不一致时的相位差异散斑法的目标函数;验证了相位差异散斑法提高图像分辨率的能力。分别用采集到的单帧

3帧

10帧图像进行PDS运算并分析结果

与基本的相位差异法相比

多帧相位差异散斑成像所恢复的图像质量有很大的提高。

Abstract

Image capaturing and image restoration implentmented by Phase-diverse Speckle(PDS) were researched in this paper.A PDS experimental platform with two cameras was designed for the extended object in our lab. Two cameras were taken to capture the short-expose images in focus and defocus simultaneously and a deformable mirror was used to construct optics system error.Then an electrical dryer was used to simulate the atmosphere turbulence. The problems from the two cameras were compared with that from single camera. Furthermore

the PD destination function was derived when the two cameras have different readout noises and how to solve the image rotation between the multi-channels was given. Finally

the capability of PDS method for image resolution improvement was validated. The PDS processes by single frame

3 frames and 10 frames were execussed

respectively

and results show that the PDS technique can generate images with highly improved quality compared with the traditional PD method.
