Abstract: | A portable Michelson interferometer for remote optical sensing with imaging capability is developed based on a laser pointer and experimentally studied. The setup has an open sensing arm with a mirror that can be attached to any object for the measurement of responses such as microdisplacement, strain, stress, and temperature. A mirror in the reference arm is mounted on an encoded stepper motor, which can operate under remote control via Web/Internet for reset and calibration. Remote microdisplacement measurements precise to within 5 μm have been performed. |
