频闪照明图像采集法及涂料脉冲发光时间影响

A method of image acquisition method based on stroboscopic illumination was proposed for measurement of pressure sensitive paint applied to rotating model. In accordance with this method， a measurement system was developed. A small fan was used as the object for the image acquisition experiment， which examined the influence of the paint pulse luminescence time on the quality of the image. The results showed that: when the image motion blur length was not greater than 4 pixels， the image clarity was essentially the same as the reference image in the static condition; with a consistent total paint luminescence time， the shorter paint pulse luminescence time indicated the lower image noise level and the higher signal-to-noise ratio，making it suitable for rotating objects with high speed.
