查询词典 diffract

When laser light strikes the surface of a tiny reflective display chip, made from liquid-crystal on silicon, the crystals both diffract the beams and alter the phase of the light waves, creating images that are in focus at all distances from the projector.

OTH-SW systems diffract radar waves around the Earth along the surface of the ocean, allowing them to travel beyond the traditional radar horizon.

OTH-SW系统沿着海洋表面绕地球衍射雷达波，使雷达波能够在传统的雷达水平线以下传送。

A detector array target of laser distant-field detect system is designed, and two key factors are analyzed. To determine the size of the array target, the laser diffract effect and the influence of atmospheric turbulence are discussed, three factors that influence the resolution of the array target are analyzed. Three factors are the dimension of laser speckle resulted by atmospheric turbulence, space sampling frequency based on sampling theory and the loss of the frequency spectrum function of the array detector.
