Fiber optic atomic force microscope (FOAFM).

Fresnel formulas. Reflection and refraction of the 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 the light on the glass prism.

Fraunhofer diffraction.

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

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.

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

The ruby laser. The laser generation is excited in a ruby rod under the action of 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.
