Researching Contrast Change in the Vibrating Pair Strokes Image By Means of the CCD-Photodetector

The initiation of zero contrast is analyzed at vibration of pair parallel strokes with various spatial frequencies across an optical axis by means of the CCD-photodetector. The formula used to calculate the contrast in the strokes’ image is specified. It is established that O’Neil theory coincides with the experimental results received by means of the CCD-photodetector when stroboscopic effect is available and time of exposition is equal to period of the frame.
Key words: structure of the optical image, frequency-contrast characteristic, contrast, CCD-photodetector, stroboscopic effect.
