faculous region meaning in English
光斑区
Examples
- The laser power is detected through the pd ’ s movement across the faculous region . when the value of the peak value of laser power is got , the power of the facular boundary points can be found according to definition of the facular boundary such as “ 1 / e ~ 2 ” theory . then the equation of the facular boundary can be made fitting by using the least square method , and calculate the beam divergence at last
采用两个光电探测器分别检测光束不同高度上的两个光斑,在确定光斑中心最大光强值后,根据光斑截面尺寸的1 / e2定义,得到光斑截面边界点的光强值,并以其为标准判定光斑截面的边界点,对探测到的边界点通过最小二乘法进行拟合,得到椭圆光斑截面的方程,根据空间几何关系求出发散角。
