Geometrical Optics and Image Quality

Course Description

Learn a modern treatment of geometrical and image-forming optics, including cardinal points, marginal and chief rays, stops and pupils, F/# and field of view, paraxial raytracing, real raytracing, paraxial radiometry for flux transfer calculations, Seidel aberration contributions and interpretation of aberrations. Discover their impact on the image quality, estimation of image quality in terms of spot size and description of image quality in terms of modulation transfer function (MTF).

How You Will Benefit

  • Understand the fundamental terminology and concepts involved with image-forming optical systems.

  • Determine by calculation the paraxial properties of an optical system: cardinal points, image-plane location, magnification, Lagrange invariant, F/# and field of view.

  • Understand terminology and units for paraxial incoherent radiometry.

  • Estimate image-plane irradiance for given source configuration.

  • Understand the origin and nature of the third-order monochromatic aberrations as well as the first-order chromatic aberrations, emphasizing their impact on image quality and their dependencies on aperture and field.

  • Estimate image quality in terms of spot size for simple systems, including effects of diffraction and aberrations.

  • Understand the concept of modulation transfer function (MTF) as a descriptor of image quality, for both optical systems and electro-optical systems.
