The program

Instrumental optics reminder

  • Geometric characteristics of optical systems
  • Magnification - Aperture - Resolution - Field of view - Depth of field
  • Reminder about aberrations


  • Reminder on photometric quantities: flux, illumination, intensity, luminance, geometric extended
  • Photometry instruments
  • Reminder about cameras and matrix detectors

Analysis of an optical system

  • Criteria qualities of an optical imaging system : defects of the wavefront, PSF, MTF
  • Measurement methods of these criteria: star test, wavefront analyzers
  • Basic principles in adaptive optics

Study conventional optical combinations

  • Diopter systems: from simple lens objectives to high quality photographic objectives
  • Catadioptric systems: telescope mirrors 2 or 3, on- and off-axis
  • Lenses with variable focal (zoom)
  • Optical systems for thermal infrared


  • Aberration measurements (star test)
  • wavefront analysis (Zygo, Haso)
  • FTM measurements (LSF, Foucault method)
