Small laser/optical distance meter that also utilizes its laser beam for data transmission. Phase based measurement of distance can be tailored to provide accuracy from millimeter to micrometer levels depending upon the application.

• The instrument successfully measured distances <1mm.
• The tool transmitted data at 5kBPS

• Permanently installed Safety Monitoring Metrology for large structures, e.g., a bridge subjected to dynamic motions and vibrations from traffic, wind load or earthquake. Provides an historical record of the structure's integrity and reduces technician involvement installing temporary monitors
• Dimensional control during assembly of large structures
• Phase based detection can provide for a low probability-of-intercept laser communication system.

• Microsatellite Arrays - Formation Flying and inter-satellite communication.
• Rendezvous/Docking of spacecraft.
• When fully miniaturized to a size similar to an industrial color CCD camera, the sensor will be suitable for numerous other metrology applications
