In this talk we review and introduce some of the examples of successful applications of the Fourier transform method (FTM) of fringe pattern analysis to the measurements of extreme physical phenomena, such as those involving ultra fast optical pulses, extremely small atomic displacements, and unconventional electron wave or EUV light, and show how the advantages of FTM are exploited in these cutting edge application areas.

This paper presents a technique that reaches 3-D shape measurement speed beyond the digital-lightprocessing (DLP) projector's projection speed. In particular, a "solid-state" binary structured pattern is generated with each micro-mirror pixel always being at one status (ON or OFF). By this means, any time segment of projection can represent the whole signal, thus the exposure time can be shorter than the projection time. A sinusoidal fringe pattern is generated by properly defocusing a binary one, and the Fourier fringe analysis means is used for 3-D shape recovery. We have successfully reached 4,000 Hz rate (80 µs exposure time) 3-D shape measurement speed with an off-the-shelf DLP projector.
