Abstract
A new method of fringe analysis by subfringe integration algorithm (SIA) is proposed to analyze moire deflectograms and to map the phase object, in which the fringe phase is retrieved and phase object message is obtained automatically. Optical tomography is applied to the moire deflectometry for the measurement of asymmetric phase object. The convolution backprojection algorithm is used to obtain the 3-D temperature field. Theoretical analysis, experimental result and simulation calculations are presented.
