Abstract

The fluctuations of spatially filtered starlight contain information about refractive turbulence strength (C(2)(n)) at the spatial filter wavenumber. If the turbulence at different heights in the atmosphere is moving at different speeds, the contribution to the fluctuations from those heights will occur at different frequencies. Therefore, the C(2)(n) profile can be inferred from the power spectrum of the fluctuations and the wind velocity profile. Vertical resolution is expected to be in the range of several hundred meters to about a kilometer. Turbulence strength measurements to better than 50% should be easily obtainable.

摘要

空间滤波星光的波动包含了空间滤波器波数处的折射湍流强度（C(2)(n)）信息。如果大气中不同高度的湍流以不同速度移动，那么这些高度对波动的贡献将出现在不同频率上。因此，可以从波动的功率谱和风速剖面推断出C(2)(n)剖面。垂直分辨率预计在几百米到约一公里的范围内。湍流强度测量精度优于50%应该很容易实现。
