Hours: 3 An introduction to optical principles – Conjugates (stops and pupils, objects and images), one skew ray, Lagrange invariant, Helmholtz invariant, Nyquist interval in an optical system. Fourier transforms with optical elements – From Maxwell’s equations to a Fourier Transform (conservation of energy, polarization, temporal coherence, spatial coherence - VanCittert Zernike), wavelength, focal length, aperture dimensions.Sampling the optical image – The transducer and its effects, follow the power - a spatial, spectral, temporal integral.What have I done – What did I set out to do, how uncertain is what I did.
