Abstract
The purpose of the study is experimental investigation about measurement error of heat flux by deflection effect in interferometric temperature imaging method. Distortion of the image taken by same lens-camera system as the previous interferometry through water with a temperature gradient was tested. The displacement in the image was 4-24μm with large scatter, and showed a similar tendency to a theoretical expectation. The deflection effect will be confirmed quantitatively and improvement method of the laser interferometer will be studied.
