TL;DR: A canonical deep space optical communications transceiver which makes synergistic use of advanced technologies to reduce size, weight, power and cost has been designed and is currently under fabrication and test as mentioned in this paper.

TL;DR: In this article, the authors used adaptive optics techniques to correct wave front aberrations caused by atmospheric turbulence and enable near-diffraction-limited performance of the receiving telescope, which facilitates spatial filtering, and allows the receiver field-of-view and hence the noise from the sky background to be reduced.

TL;DR: In this paper, the authors describe the current performance of an adaptive optics testbed for optical communication, which allows for simulation of night and day-time observing on a 1 meter telescope with a 97 actuator deformable mirror.

TL;DR: The Optical Ground Station 1 (OGS1) as discussed by the authors is the first dedicated ground terminal to support NASA's developing space-based optical communications infrastructure, which is based at NASA's Optical Communications Telescope Laboratory (OCTL) at the Table Mountain Observatory near Wrightwood, CA.

TL;DR: A detailed description of the experiment design for the uplink optical channel, in which 4 beacon lasers and 3 modulated communication lasers were combined and projected through the F/76 OCTL main telescope, is provided.
