SUMMARYImage analysis methods are first classified into four groups of theories related to optics, after which the associate hypotheses, the structures, the laboratory equipment and the mathematical framework for one of them, better known by the term of morphological optics, are studied in detail.

Patients with signs and symptoms consistent with acute monosymptomatic optic neuritis should undergo evaluation with gadolinium-enhanced MRI of the brain and orbits to determine whether or not they are at high risk for the development of clinically definite multiple sclerosis (CDMS).

Optic Nerves, Optic Chiasm, and Optic Tracts
1988The vertebrate optic nerves, optic chiasm, and optic tracts contain axons of retinal ganglion cells. These axons connect the retina, where light absorption produces patterned neuronal firing, to the brain, where these firing patterns can undergo further processing.

Physical Optics, Wave Optics, and Fourier Optics
1991When any of the dimensions or sizes of the components in an optical system is on the order of wavelength, then the methods discussed under geometrical optics do not give the proper solution to the problem. For this case, we must start from Maxwell’s equations, and derive the wave equation from which the proper solution to this problem can be obtained.

Linear optical characterization of nonlinear optical polymers for integrated optics
Macromolecular Chemistry and Physics, 1998Conjugated X (3) - active polythiophenes and polybenzobisthiazoles were characterized with respect to linear optical properties like refractive indices and linear absorption coefficients. The contributions of different alkyl side chains to optical properties are discussed for polythiophenes. The materials are discussed with respect to their ability as

Optical Bistability and the Digital Optical Computer
Topical Meeting on Optical Bistability (OB3), 1985Electrons are well suited for switching operations as they occur in a logic processor. But electrons are not so easy to guide from one point to another point. On that score, photons are more suitable. Recently, photons became amendable also for logic processing. Hence, the stage is set for the development of an all-optical digital computer.
