并行激光散斑测速技术中光学参数之间的制约关系

Restrictive relationships of optical parameters in parallel laser speckle velocimetry

分析了采用透镜阵列做为处理器件的并行激光散斑测速系统中散斑照相机的孔径、两次傅氏变换的焦距、阵列间距、液晶光阀和摄像机ＣＣＤ的尺寸和分辨率等参数之间的相互制约关系；提出了参数的选取方案，并给出了参数选取实例。

The restrictive relationships of several optical parameters in parallel laser speckle velocimetry using hololens array are analyzed. The selecting program of array pitch, camera aperture, focal length of Fourier lens, size and resolution of LCLV and CCD is presented. The feasibility of parallel optical processing method is proved through example calculation.
