【Abstract】 The conical refraction effect of biaxial crystal is studied deeply. Dynamic conic refraction of any conical angle within the range of 0～25° is obtained using KNbO 3 crystal with a single pin hole aperture. The principles of conical refractional scanning (CRS) and a novel laser CRS instrument are developed. Spatial CRS within modulated conical angle is realized.更多还原
