Lippmann–Bragg broadband holographic mirrors

Animal Eyes and Video Surveillance

“…15(a)) rather than on quadratic one, as in the case of HE-interference filters. Therefore, they are closer to holographic Bragg mirrors, such as those based on dichromatic gelatin (DCG) (Jannson et al, 1991), which is volume holographic material, extracted from biologic tissues. Then, Kogelnik's coupled-wave theory (Kogelnik, 2001) holds, with coupling constant, ν, defined as: ν = πΔn⋅T/λ′, where Δn is index modulation and T-grating thickness, as in Fig.…”

Holographic Waveguide Array Rollable Display.

“…The second issue is using waveguide hologram recording techniques to generate input and output coupling hologram arrays. Both of these approaches are based on POC's previously developed polymer waveguide technology [3] and planar holographic technologies [4,5]. This final report describes POC's progress in the Phase I feasibility study based on holographic optics and multilayer polymer waveguide substrate.…”

“…POC had already developed computer simulation models for a general hologram/multilayer hybrid structure for the Bragg and Raman-Nath cases [4]. POC had also developed a general 3-D computer model for designing a holographic waveguide coupler, and also a general radiometric ray tracing (R 2 T) model to simulate propagation of light from a general light source with arbitrary coherence properties [7].…”

“…These technologies include polymer waveguide arrays for high density optical interconnects [31, multilayer holographic polymer mirror design and fabrication [4], planar holographic input, output, and beam routing techniques [5], and the polymer embossing technology for holographic light shaping diffusers and LCD backlighting panels (these are already POC commercial product lines).…”

“…2A cos e 0 = X 0 , (3)(4)(5)(6) where X is the wavelength and 0 is the angle of incidence of the laser beam (Figure 3-26).…”
