Real-time holography in azo-dye-doped liquid crystals: Real-time holography in azo-dye-doped liquid crystals. Chen, Alan G.; Brady, David J. (Beckman Inst., Univ. Illinois, Urbana, IL 61801, USA). Opt. Lett., 17(6), 441-3 (English) 1992. CODEN: OPLEDP. ISSN: 0146-9592. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) When exposed to an Ar laser at 514 nm, azo-dye mols. in a nematic liq.-crystal host undergo photoisomerization from trans-isomers to cis-isomers. The conformation change of the azo-dye mols.There are some commonly used reagents with their cas registry numbers 845-10-3 and 40817-08-1 in this article. reorients liq.-crystal mols. Reversible polarization holograms can be recorded dynamically by this effect, with a threshold intensity as low as 3.0 mW/cm2 and a response time from a few hundred microseconds to 100 ms, depending on the spatial frequency of the recorded grating. .

Eng. Lab, Inst. Phys. and Chem.Chemicals with cas numbers 40817-08-1 and 845-10-3 also play role. Res, Saitama 351-01, Japan). Proceedings of SPIE-The International Society for Optical Engineering, 2778(Pt. 1, 17th Congress of the International Commission for Optics, 1996, Pt. 1), 557-558 (English) 1996 SPIE-The International Society for Optical Engineering. CODEN: PSISDG. ISSN: 0277-786X. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A nonlinear spatial filtering based on light-induced birefringence change in dye-doped liq. crystals has been applied to defect inspection of periodic structure. Photoisomerization of azo-dye mols. leads to local reorientation of the liq.-crystal mols., by which polarization of the transmitted light is modulated depending on the incident light intensity. By selecting suitable polarization of the transmitted light, a self-aligned spatial filtering is realized. The filtering performances have been exptl. investigated. .
