【摘要】 通过对锥形折射效应的深入研究， 采用单个针孔和ＫＮｂ Ｏ３ 双轴晶体， 首次获得大角度任意锥角的动态外锥折射。实验证明了外锥折射锥角与入射光会聚角度之间的关系为１∶１ ， 依据此关系， 改变会聚光角度， 研制出圆锥角被调制的外锥折射扫描器件， 实现大角度大屏幕激光圆锥扫描。可应用于激光雷达、测距、驾束制导、扫描成像等技术中。更多还原

【Abstract】 IN this paper,the conic refraction effect of biaxial crystal is studied deeply. A dynamic conic refraction of any conical angle within the range of 0°～25° is obtained for the first time using kN bO 3 crystal with a single pin hole aperture.The principles of Conic Refractional Scanning are set up. a noval laser CRS instrument is created. Spatial CRS within which the conical angle can be modulated is laser technigue of conic refraction effect.更多还原
