论文摘要
对于不可能使用光纤而需要高带宽的遥远应用，可用空间通信（FSO）很有趣。但是，这些链接必须面对几个问题，最重要的是，由于湍流介质的传播，大气的繁殖，束闪烁。已经制定了几种缓解策略，但是抑制闪烁的最佳方法是使用自适应光学器件，该光学元件现在广泛用于天文学。 FSO的主要困难是足够快地探测波前以进行良好的湍流校正。由于缺乏在SWIR中工作的波前传感器，这是不可能的。 C-RED 3是一个640x512 SWIR摄像机，在600fps的全帧中运行，并且具有FSO的特定功能（低交换，低成本）的特定功能，具有天文红外快速传感器的所有发展。我们将介绍这款新相机的性能，并演示其如何满足FSO自适应光学的需求。
Free space communications (FSO) is interesting for distant applications where high bandwidth is needed while using a fiber is not possible. However these links have to face several issues, and the most important one is the beam scintillation due to the propagation through a turbulent media, the atmosphere. Several mitigation strategies have been developed, but the best way to suppress scintillation is to use adaptive optics, widely used now in astronomy. The main difficulty for FSO is to probe the wavefront fast enough to have a good turbulence correction. This was not possible due to the lack of wavefront sensors working in the SWIR. C-RED 3 is a 640x512 SWIR camera running at 600FPS full frame and has the legacy of all the developments of astronomical infrared fast wavefront sensors on top of specific features for FSO (Low SWaP, Low Cost). We will present the performances of this new camera and demonstrate how it fulfills the needs of FSO adaptive optics.
