LASER BASED SENSOR AND TELEMETRY SYSTEM

摘要

LASER BASED SENSOR AND TELEMETRY SYSTEMAbstract of the DisclosureA transducer defined by a laser is set forth.Strain, movement, velocity, temperature, pressure, andvibration coupled to the laser change the lasing frequency orform a Doppler shift. The laser is thus installed at aspecified location to couple a measured phenomenon and therebyenable transmission of the encoded variable in the laser beam.A receiver located remote from the laser picks up the beam fordata retrieval.
