Therefore, different incident angles cause different propagation distances of light, which eventually results in an interference fringe in the vertical direction of the photoelectric detector.
where I(x, y), a(x, y), b(x, y), [phi](x, y), and (x, y) are the interference fringe pattern intensity, the background illumination, the modulation amplitude, the phase term, and the spatial coordinates of the surface under test, respectively.
However, there exists a resolution limit; the minimum period of the interference fringe is 6/2 for a conventional light source.
The interference fringe pattern can be finely tuned by adjusting the loss strength of the two coupling regions and their separation.
This means that the zero order interference fringe has linear polarization, being the electric field perpendicular to the y-z plane.
where [alpha] is the rotation angle of the analyzer rotated until the innermost interference fringe merged using a Sennarmont compensator in a compensator slot, n is the number of interference fringe.
The technique uses two lasers set up so that their beams intersect at a point in space and produce an interference fringe pattern.
In addition, if white light is used, by noting the progression of the spectrum of interference fringe colors you can determine whether the specimen surface is rising or falling in the area being viewed.
Using the fringe cycle method, the coordinate value on the Z-axis with the maximum local focus measure is taken as the height of each pixel, generating an interference fringe on the surface of the object with a two beam interference objective lens.
In addition, because the bi-prisms are adjustable independently, the field of view and interference fringe spacing can now be controlled independently.
The interference fringe can be aligned using the TIC slider without time-consuming sample orientation normally associated with polarization interferometers, according to the company.
