This paper presents a new approach to fringe pattern profilometry. In this paper, a generalized model describing the relationship between the projected fringe pattern and the deformed fringe pattern is derived, in which the projected fringe pattern can be arbitrary rather than being limited to being sinusoidal, as are those for the conventional approaches. Based on this model, what is believed ...

Formal analysis remains outside the mainstream of system design practice. Interactive methods and tools are regarded by some to be on the margin of useful research in this area. Although it may seem relatively academic to some, it is vital that this the so-called “theorem proving approach” continue to be as vigorously explored as approaches favoring highly automated reasoning. Design derivation...

A single-image fringe projection profiling method suitable for dynamic applications was developed by combining an accurate camera calibration procedure and improved phase extraction procedures. The improved phase extraction process used a modified Hilbert transform with Laplacian pyramid algorithms to improve measurement accuracy. The camera calibration method used an accurate pinhole camera mo...

This paper offers a new way of estimating workers’ valuation of fringe benefits using data on workers’ choices among fringe benefits packages offered by the employer. This approach overcomes both the omitted variable problem and the identification problem that bias estimates of compensating differentials and supply and demand parameters for fringe benefits from the traditional hedonic model mos...

This paper is a theoretical analysis of mirror tilt in a Michelson interferometer and its effect on the radiant flux over the active area of a rectangular photodetector or image sensor pixel. It is relevant to sensor applications using homodyne interferometry where these opto-electronic devices are employed for partial fringe counting. Formulas are derived for radiant flux across the detector f...
