Optical channel communication for laser rangefinders or other mobile optical devices

A system to communicate with one or more remote systems, wherein the one or more remote systems comprise one or more systems each of which is different than the system, the system comprising:

• a line-of-sight communication interface capable of communication with the one or more remote systems when at least one optical receiver of the system has line of sight to one or more light-transmission modules of the one or more remote systems, respectively;
• and
• processing circuity to, in response to the at least one optical receiver capturing light transmitted over-the-air by the one or more light-transmission modules, perform operations comprising:
• recover one or more values from the light;
• and
• display the recovered one or more values, or information derived therefrom, on an electronic display, or
• using one or more local LEDs or another light-generating device, transmit light representative of the one or more values, or representative of the information derived therefrom, to a remote laser rangefinder or another remote mobile optical device having processing circuitry to recover one or more values from the transmitted light.
