Abstract

Photothermal technique for sensing pressure in a cell is reported. The pressure is monitored from the frequency change of the vibration of the cell itself. The vibration is generated by the photothermal bending effect caused by the chopped laser irradiation, and it is sensed by the deflection of the probe laser beam. The proposed technique is noncontact, and thus it will be useful for remote pressure measurements in hostile environments.
