I would like to know how the physics(and possibly mathematics) for how quarter-wave stacks could be utilized to make an ideal rejection filter that rejects all visible coherent green or blue or red laser light, not at the same time, in a given narrow spectral wavelength range (10 nanometers to 20 nanometers wide) and transmits everything else within the visible light band.
I have read some optics books on the analysis of quarter wave plates for normal incidence. I analyzed how the Boeing 757 aircraft's nose geometry forces incoming laser rays aimed from the ground on approach to hit the cockpit window at large angles of incidence and high orders of interference. If you would like to see this analysis , I will post it as an image. So, I would be interested in how to analyze the blocking and transmission properties of quarter-wave stacks at large angles of incidence.
Also, I would like to know the relationship between coherence length of visible light laser pointer beams and the distance between quarter wave plates so we could discriminate between coherent and incoherent light over a very narrow wavelength range.
The reason I ask this question is because I read Fred Goldstein's chapter, Optical Filters , in the book "Geometrical and Instrumental Optics" edited by Daniel Malacara and published by Academic Press in 1988. In Section 6.3.4 , page 294 , Fred Goldstein wrote that, "There is interest in filters which reject in an extremely narrow spectral regions. These could be superior to current filters utilized for eye protection near lasers. In theory, such filters can be constructed from a great number of quarter-wave layers of materials with nearly identical indices.[EDIT June 8 2016 Why?] Inhomogenous films with periodic index variations represent another possiblity. [EDIT June 8 2016 Why?]"
I believe that matrix and Fourier transform formalism may be necessary here. Please correct me if I am wrong.
Any help is greatly appreciated.
