Coherent summation of laser beams using binary phase gratings
Autor: Wilfrid B. Veldkamp, James R. Leger, Gary J. Swanson
Publikováno v: Optics letters. 11(5)
A method for coherent addition of lasers is presented that uses binary phase-only gratings. It is shown that a grating that splits a single beam into N equal orders with high efficiency can be used in reverse to convert N laser beams into a single be

Interferometric recording of high-quality zone plates in spatially incoherent illumination
Autor: Gary J. Swanson
Publikováno v: Optics letters. 8(1)
An interferometer capable of producing high-quality off-axis zone plates in spatially incoherent light is described. An example is shown that demonstrates the noise-suppressing ability of the spatially incoherent process.

High-precision surface profiling with broadband accordion fringe interferometry
Autor: Matthew P. Kavalauskas, Gary J. Swanson, Lyle G. Shirley
Publikováno v: SPIE Proceedings.
Accordion fringe interferometry (AFI) is an active-triangulation, surface-profiling technique based on projecting interference fringes onto the surface of an object from a source at one location and viewing with a camera at another location. Interfer
