Learning outcomes

The course provides basic theoretical and laboratory knowledge of the fundamental phenomena of optics (geometric/wave optics) and the principle concepts of acoustics. The central objectives of the course include an understanding of the physical phenomena that occur during a typical photographic process, the ability to quantify photographic quantities, and to find and utilize computational relationships in photographic imaging.

 

General Competences

  • Search for, analysis and synthesis of data and information, with the use of necessary technology.
  • Decision making.
  • Team work.
  • Criticism and self criticism.
  • Production of free, creative and inductive thinking.

 

Course Outline

THEORY

  • Light, light theories
  • The physical phenomena of reflection, refraction, diffusion, scattering, total reflection, absorption
  • Prisms, dispersion of light
  • Optical instruments, optical systems, mirror-lens compound optical systems
  • Photographic lens, characteristics, lens aberrations (spherical / chromatic)
  • Magnification – magnifying lens, principle of operation, calculations
  • Depth of field determination, description, calculations
  • Color, color theories, photographic filters, absorption curves
  • Sound, sound waves, characteristics of sound, speed of sound
  • Human hearing and speech
  • Acoustics, Sound intensity and intensity scales, Room Acoustics

 

LABORATORY

Exercises – indicative titles:

  • Theoretical exercise (computational)
  • Calculation of the (unknown) focal length of a thin lens
  • Principle of operation of a camera
  • Linear magnification of a photographic lens
  • Calculation of the refractive index of the material in an optical prism
  • Measurement of the radii of curvature of refractive surfaces in lenses
  • Measurement of speed of sound in air.

 

Laboratory exercises are performed using experimental devices such as: Spectroscopes, Optical benches, Laser devices, Generators, Oscilloscopes, etc.
