Learning outcomes of the course unit
Explanation of the basic study principles of radant (geometric) optics, on which optical elements and systems are based. Their application in cinematic and television image devices and equipment in particular. To provide a basis for their further study and practice.
Mode of study
Prerequisites and co-requisites
Pre-college level of awareness, appropriate knowledge of mathematics, notion of cinematic and television technology.
- Light and its properties.
The wave nature of light (amplitude, phase, frequency). Ray and wavefront. Polarization of light. Refraction and reflection of light. Fresnel formulae.
- Basic properties of the optical material.
Index of refraction, absorption and transmission of the materials. Dispersion (Abbe number) and birefringence of the materials
- Optical imaging
The optical system. An ideal optical system. The principal and focal points and planes of the optical system. Focal length. Image equations (conjugate distance equations). Magnification optical system. The thick and thin lens and its properties.
- Aberrations of optical systems
Wave and ray aberrations. Spherical aberration, coma, field curvature, astigmatism and distortion. Chromatic aberrations.
- Photometric properties of the optical system
Aperture stop, entrance and exit pupil of the optical systems. F-number and numerical aperture of the optical systems. Vignetting ray beams in the optical system and Field of view. Depth of focus optical system. Basic photometric quantities and units. Photometric properties of the optical system.
- Two-component system
Telescopes (Kepler and Galilean telescopes) and microscope. Afocal attachments.
- Image quality
Point spread function (PSF), Airy disk, optical transfer function (OTF, MTF). PSF and MTF for aberration free optical system with circular aperture. Resolution of the optical systems.
- Sources and detectors of radiations
Thermal source of the light, chromatic temperature, natural and artifical sources. Eye and its properties. Modern detectors of radiation.
- Optical components and systems
Lenses, mirrors, absorption filters (color and neutral), polarization filters (linear, circular), splitters, prisms, light guides (fibre optics). Basic types of photographic lenses (Triplet, Tessar, Planar, Petzval lens, Fisheye lens, converters etc.) and their properties. Zoom lenses and their properties.
- Methods for measuring the basic parameters of optical systems
Collimator, autocollimator and measuring microscope. Measurement of the focal length, location of focus, magnification, position and size of the pupils of the optical systems. Measuring of the point spread functions (PSF) and modulation transfer function (MTF). Measurement of photometric properties of the optical systems.
Pre-supposed knowledge: pre-college knowledge of math and physics.
This course is devoted to the basics of optics as one of the pivotal scientific-technological disciplines of image technology, particularly cinematography and television. Individual topics will be used to explain the classic principles on which optical elements and systems are based, their application in established professions, practice procedures and basic measurement methods.
