Photo-thermoelastic mechanical beam chopper at a low frequency

K. Hane, T. Kanie, S. Hattori

Research output: Contribution to journalArticlepeer-review


A simple beam chopper advantageously using the thermoelastic bending due to photothermal effect is reported. The mechanical vibration for chopping is generated due to the modulated irradiation from a laser diode so that the chopper is remotely operated.
