Automatic calibration method for phase shift shadow moire interferometry.
A new calibration procedure for phase shift moire interferometry is proposed. The method does not ask for a high precision machined calibration object and makes use only of the moire setup itself. The procedure is fast and fully automatic. The fringe plane distance lambda was determined with a precision of 1.3%. We present control measurements on a plane surface and a perfect sphere confirming the value and the precision of lambda.
