The polarization images is calculated by using polarized optical image(POL) equation. The wing flapping mechanism can be improved by polarization images. This study uses two types of light sources and compares with laser and white light source. In measurement, we change the incident angle and reflection angle for image detection. The incident angle and receiver angle is controlled by the motorized stages. The wing membrane changing images, wing membrane, flapping frequency ,wings changing angle and flow field have been measured. This study can be used for static measurements and also be applied to dynamic measurements. The optical measurement is a wide range of applications of the optical measurement system.
