Abstract
A pressure sensor includes an optical transmitter transmitting a dispersive light toward two optical receivers, all carried in a housing. Pressure changes on the housing cause the light beam to be deflected with the amount of deflection measured by the difference in light received by each of the two receivers. A processor operable with the receivers provides a pressure measurement responsive to the light beam deflection.
