Abstract
The laser speckle velocimeter based on the zero-crossing rate of the spatially integrated speckle intensity variations is studied under various optical configurations of illumination and detection. The eliminating method of the additional noise is also experimentally investigated by using Schmitt trigger circuits for the counting of zero-crossings.
