Contents
- Basic types of the camera lenses
Imaging and photometric properties of the basic types of the camera lenses. The criterion of the quality of the camera lenses (PSF, MTF). Comparison of properties of various types of the photographic lenses. Supplementary lenses (Converters). Methods for measuring the basic parameters and image quality of the photographic lenses (focal length, location of the focal points, magnification, PSF, MTF).
- Zoom lenses
Basic properties and construction of the zoom lenses. The macro-lens, their structure and properties. Image-space (or image-side) telecentric lenses. Image stabilizer and autofocus systems.
- The quality of the photographic lenses evaluation
Measurement of the focal length and the position of focal points of the optical systems. Measurement of lens distortions. Measurement resolution of the optical systems, point spread function, modulation transfer function and spectral properties of lenses. Measurement stability of the image position of the zoom lenses.
- Wave optics
Basic concepts of wave optics. Velocity of the light in vacuum. The refractive index of the optical materials and its dependence on the wavelength of light. Abbe number of optical glass. Light as electromagnetic waves. Amplitude, phase, polarization, wavelength and frequency of waves.
- Interference of light
Coherence of light. Two-beam interference of light. Young interference experiment. Interference in thin dielectric layers. Antireflection coatings, principle and their effect on reducing stray light, contrast and color matching lenses. Interference filters and their properties.
- Diffraction of light
What is diffraction of light. Diffraction of light by a circular and a rectangular hole. Influence of diffraction on the optical imaging quality. Point spread function (PSF) of the optical system. Airy disc and its size. Rayleigh criterion. Resolution of the optical systems. Modulation transfer function of the optical system (MTF) and its importance in the theory of optical imaging. Diffractive optical elements and their application in cinema.
