Abstract

The OCTL to OICETS Optical Link Experiment (OTOOLE) project demonstrated bi-directional optical communications between the JAXA Optical Inter-orbit Communications Engineering Test Satellite (OICETS) spacecraft and the NASA Optical Communications Telescope Laboratory (OCTL) ground station. This paper provides 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. The paper also describes the reimaging optical design employed on the acquisition telescope for receiving the OICETS-transmitted signal and the design of the receiver channel. Performance tests and alignment techniques of both systems are described.
