Le programme
Instrumental optics reminder
- Geometric characteristics of optical systems
- Magnification - Aperture - Resolution - Field of view - Depth of field
- Reminder about aberrations
Photometry
- 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
Labwork
- Aberration measurements (star test)
- wavefront analysis (Zygo, Haso)
- FTM measurements (LSF, Foucault method)
