Measurement of high-dynamic temperature field usinghigh-speed quadriwave lateral shearing interferometer
An approach to measure a high-dynamic two-dimensional (2D) temperature field using a high-speed quadriwave lat-eral shearing interferometer (QWLSI) is proposed. The detailed theoretical derivation to express the wavefront recon-struct principle of the proposed method is presented. The comparison experiment with thermocouples shows that the temperature field measurement using QWLSI has a precision of ±0.5 °C. An experiment for measuring the high-dynamic temperature field generated by an electrical heater is carried out. A 200 frame rate temperature field video with 512 × 512 resolution is obtained finally. Experimental results show that the temperature field measurement sys-tem using a QWLSI has the advantage of high sensitivity and high resolution.
