Phase retardation measurements in polarization and interference microscopy, theory and application of phase modulated light methods, and design of photoelectric microscope
Ultraviolet microscopy is used by cytologists and biochemists to study the morphological and physiological changes in the living cell under varied culture conditions. The yeast cell is used because of its content of ultraviolet absorbing materials and its lack of motility.
Oxidation of Al-2 percent aluminum oxide SAP TYPE alloy foil heated in situ and observed by hot stage transmission microscopy, electron diffraction and motion picture micrography
Color television microscopy used at laboratory range magnifications, reproduces a slide image with sufficient fidelity for medical laboratory and instructional use. The system is used for instant pathological reporting between operating room and remotely located pathologist viewing a biopsy through this medium.
