一种新的散射光角分布测量技术
A NEW METHOD FOR MEASURING SCATTERINGLIGHT ANGULAR DISTRIBUTION
【摘要】 利用特殊研制的凹椭球面反射镜将激光打靶产生的散射光引出真空靶室收入装有胶片的暗盒,对散射光角分布进行精细测量,给出了在靶后2π空间立体角内散射光角分布的三维立体曲线,散射光角分布测量精度达±3°
【Abstract】 One can usually measure the scattering light in laser plasma interaction through the PIN or pyroelectric detector which is discreted in chamber for the measure of light angular dependence. It is the main diagnostic tool for the scattering light but is difficult to obtain the actual angular dependence because of the finite observation point. This paper reports a new way which correct all of the scattering light through concave mirror and record the scattering light space distribution on film. Consequently the scattering light intensity angular dependence can obtained.
