Fiber optic atomic force microscope (FOAFM).

Fresnel formulas. Reflection and refraction of a light beam on the boundary surface between two substances - glass with refractive index n=1.5 and air with refractive index n=1.0

Linearly and elliptically polarized light. Imaging ellipsometry.

Dispersion of light on a glass prism.

Fraunhofer diffraction.

Photothermal excitation of microresonator by modulated optical radiation from a glass fiber.

The theory of color vision of Young and Helmholtz. The sensation of any color can be achieved by superposition of pure red, green and blue colors.

A Fabry-Perot fiber optic interferometer formed by the fiber end face and a movable mirror.

The ruby laser. The generation of a laser light is caused by the excitation of atoms in a ruby rod under the action of the flash of a spiral discharge lamp.

Distortion of the image in a positive lens. The direct lines running along the main optical axes of a lens are displayed as straight lines and other lines are curved outward.
