The general theory of phase shifting algorithms.
We have been reporting several new techniques of analysis and synthesis applied to Phase Shifting Interferometry (PSI). These works are based upon the Frequency Transfer Function (FTF) and how this new tool of analysis and synthesis in PSI may be applied to obtain very general results, among them; rotational invariant spectrum; complex PSI algorithms synthesis based on simpler first and second ...
متن کاملFast three-step phase-shifting algorithm.
We propose a new three-step phase-shifting algorithm, which is much faster than the traditional three-step algorithm. We achieve the speed advantage by using a simple intensity ratio function to replace the arctangent function in the traditional algorithm. The phase error caused by this new algorithm is compensated for by use of a lookup table. Our experimental results show that both the new al...
متن کاملWright's Shifting Balance Theory and the Diversification of Aposematic Signals
Despite accumulating evidence for selection within natural systems, the importance of random genetic drift opposing Wright's and Fisher's views of evolution continue to be a subject of controversy. The geographical diversification of aposematic signals appears to be a suitable system to assess the factors involved in the process of adaptation since both theories were independently proposed to e...
متن کاملThe exquisite corpse: a shifting view of the shifting balance.
In 1925, a game called ‘exquisite corpse’ was invented by a group of surrealists to harness the random power of imagination through collaboration. Working either with words or drawings, an exquisite corpse was begun by one member of the group, who then folded the paper so that his or her contribution was obscured and then passed it to the next member. The game (named after one of their first re...
متن کاملRegularized multiframe phase-shifting algorithm for three-dimensional profilometry.
In many industrial inspection systems, it is required to have a high-precision three-dimensional measurement of an object under test. A popular technique is phase-measuring profilometry. In this paper, we develop some phase-shifting algorithms (PSAs). We propose a novel smoothness constraint in a regularization framework; we call this the R-PSA method and show how to obtain the desired phase me...
