Wavefront measurement for transparent object based on incoherent imaging;
基于非相干成像的透明物体波前测量方法
This technique is based on incoherent imaging and phaseshift.
这种方法采用非相干成像和相移技术,CCD摄像机经待测反射镜和相同位置处参考平面镜分别对由计算机产生的正弦光栅进行成像,通过相移技术得到各自的相位分布,从而计算出正弦光栅的相位变化。
The investigation reveals that the far-field coherent combining irradiance distribution have the multiple side-lobes pattern of non-Gaussian character while propagating in free space with weak turbulence, and it have the advantage of high peak intensity over the incoherent combining counterpart.
根据广义惠更斯-菲涅耳原理,对相干合成和非相干合成光束在湍流大气中的传输进行数值计算,并引入光束传输因子(BPF)用于评价合成光束的光束质量,对湍流大气对相干合成与非相干合成远场光束质量的影响进行定量分析。
The far-field intensity distribution for coherent combining and incoherent combining with conformal focusing transimitting is numerically calculated, and the effect of phase error, beam jitter, and fill factor is studied in detail to make a contrastive study of coherent and incoherent combining.
为了比较不同合成方案的远场效果,对聚焦发射的相干合成和非相干合成光束远场分布进行数值计算,从控制相位误差、光束抖动和阵列占空比等三方面对这两种方案的远场特性进行比较研究。
