Abstract
An alternative method for visibility measurements on interference frin ges immersed in speckle noise is presented. It is based on the intensi ty of the first order peaks obtained by digitally Fourier transforming The fringe pattern Computer simulated experiments show acceptable res ults even in the presence of highly noise speckle background.
