【摘要】 大气相干长度是研究大气湍流强度、激光大气传输以及自适应光学的重要参量之一。整层或有限距离相干长度的测量大多是以恒星、高空气球中光目标等作为信标光源的。一般依靠轨道跟踪或手动跟踪,跟踪能力差,测量时操作不便。为此研制了一套信标自动跟踪测量系统,可以实现各种不同条件下大气相干长度的自动跟踪观测,从而大大提高了测量性能。更多还原

【Abstract】 Atmospheric coherence length is one of important parameters of atmospheric turbulence, atmospheric propagation of laser and phase adjustment of adaptive optics. Because whole-air or finitied length measurement of atmospheric coherence length uses stars, object in high altitude balloon and the like movement object as indices luminous source, the tracking ability is bad. So we devoloped a suit of automatism tracking system. All kinds of atmospheric coherence length automatism measurement can be realized. Atmospheric coherence length measurement ability is improved greatly.更多还原
