✦ Synopsis

A conÿguration of reversal shear interferometer suitable for measurement of spatial coherence of high average power, large cross-section laser beam has been discussed. Ghost-less beam splitters in which unwanted multiple re ections from the surfaces have been suppressed by total internal re ection are used for beam splitting and re-combination. Advantages and drawbacks of this conÿguration have been discussed.
