Abstract
In this paper, the specifics of digital speckle intensity correlation metering (DSICM) has been discussed in detail. The dynamic range, spatial resolution and signal resolution of DSICM have been investigated theoretieally and experimentally under the conditions of cohrent and uncoherent light. The way of extending the correlation metering dynamic range and improving the correlation metering system has been presented.
