Miniature optical communication transceiver with imbedded ranging and Doppler measurement capabilities

We propose to develop a miniature optical communication transceiver with imbedded ranging and accurate Doppler capabilities. We demonstrated a high precision ranging (distance) and range rate (speed or Doppler Shift) measurement system over high speed laser communication link. A complete bench top optical communication system was built, which includes a ground terminal and a space terminal. We have demonstrated a high precision range rate measurement and absolute ranging
