PRESSURE SENSOR

摘要

A pressure sensor (10) includes an optical transmitter (14) transmitting a dispersive light toward two optical receivers (16 and 18), all carried in a housing. Pressure changes on the housing causes the light beam (20) to be deflected with the amount of deflection measured by the difference in light received by each of two receivers. A processor (24) operable with the receivers provides a pressure measurement responsive to the light beam.
