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.

A novel optical waveguide for integrated optics
IEEE Journal of Quantum Electronics, 1973A novel dielectric optical waveguide was made consisting of a guide pattern on a thin dielectric film. Almost all the power propagates in the thin film along the guide pattern. The existence of propagation modes of this waveguide was verified both theoretically and experimentally.

Neurologic Clinics, 2010
Optic neuritis usually presents with painful monocular vision loss in younger patients. Spontaneous improvement in vision occurs over weeks, and treatment with high-dose intravenous steroids increases the rate but not extent of visual recovery. Risk of progression to multiple sclerosis (MS) is largely dictated by baseline brain magnetic resonance ...

Optic neuritis usually presents with painful monocular vision loss in younger patients. Spontaneous improvement in vision occurs over weeks, and treatment with high-dose intravenous steroids increases the rate but not extent of visual recovery.

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.

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.

Annual Review of Biophysics and Biophysical Chemistry, 1991
I have traced the development of the optical method from Millikan's colorimetry of cat muscle myoglobin to today's high-frequency laser diode time-resolved phase modulation system study of hemoglobin and myoglobin in muscle and brain in adult humans. The path length as well as specific absorption information is obtained in terms of the rate of photon ...
