Real time two color variable resolution video moire and error map moire using a Mach-Zehnder interferometer
A variable resolution two color video moire system has been built which uses a dual laser illuminated Mach-Zehnder interferometer as the fringe projector. One input of the interferometer is illuminated by a He-Ne laser ...
Mach-Zehnder interferometer fringe projector for variable resolution video moire
A Mach-Zehnder based variable resolution fringe projection system has been built for 3-D video moini machine vision. This system uses the three main advantages of the Mach-Zehnder - 1) There is no optical feedback to the ...
