Abstract

It is shown that the speckle nature of electronic speckle pattern interferometry images can be reduced in quasi-real time with the use of only three consecutive video images. By use of additive–subtractive phase modulation processing the technique is essentially insensitive to environmental noise, and distortion of fringes does not occur. By further removing the random speckle phase we show, using speckle statistics, that the number of dark speckles in the resulting fringe pattern is close to zero.
