Abstract
On thermal test of aerospace research filed, wind tunnel is usually used for heating the sample up to 1 700℃. It is very difficult to measure dynamic temperature filed without using the expensive and non-flexible temperature metrical IR-camera. Based on colorimetric model, two selected near-infrared wavelengths near 900 nm were used and a high dynamic response CCD device was hired. Mechanic and optical design guaranteed space synchronization of collected images of two measurement tunnel. The device achieved temperature filed measurement, frame rate is up to 40 Hz, and the measurement accuracy is less than 6%.
