Abstract: A system for use in identifying one of an unmanned ground vehicle and an unmanned aerial vehicle includes a signal emitter associated with the unmanned vehicle. The signal emitter includes at least one quantum cascade laser. The signal emitter emits a signal having a wavelength between approximately 2 μm and approximately 30 μm, and the signal is detectable to identify the unmanned vehicle as friendly at a distance from the signal emitter greater than approximately 1 meter.

Abstract: A system for use in identifying a user includes a portable emitter transported with the user. The emitter includes a quantum cascade laser configured to emit a thermal beam identifying a location of the user in response to a command, the thermal beam having a wavelength between approximately 2 μm and approximately 30 μm.

Abstract: An example tracking signal device comprises a housing and a light source disposed within the housing. A window is defined within the housing optically downstream of the light source. The device further comprises a sensor configured to receive a first beam of radiation and a controller operably coupled to (i) the light source and (ii) the sensor. The controller is configured to control the light source to emit a second beam of radiation based at least in part on receipt of the first beam of radiation by the sensor.
