2313724 – Adaptive Optics

The first lecture will take place on November 4th 2025.

It is recommended that the students first complete the module Optical Engineering [M-ETIT-100456] (currently offered as "Optical Engineering and Machine Vision") or Fundamentals of Optics and Photonics [M-PHYS-101927] before they enroll for this course.

The students will:

get familiar with Fourier description of imaging through aberrated optical systems and random media,

understand the description of aberrations through Zernike modes,

learn how to analytically compute the effects of turbulence on various optical observables such as image/beam motion, temporal power spectra, Zernike modes, scintillation, etc.,

understand the effect of noise on various quantities and metrics pertinent to the design of adaptive optical systems,

understand the advantages and disadvantages of various schemes for wavefront sensing and correction,

1. Theory of turbulence (covariances, structure functions, power spectra, inertial range, dimensional argument of Kolmogorov)
2. Fourier optics (point-spread function, modulation transfer function)
3. Statistical optics (characteristic function, probability density function)
4. Sources and description of aberrations (Zernike polynomials, orthogonality, Marechal criterion)
5. Adaptive optics systems (open- and closed-loop systems, error budgets, tip-tilt correction)
6. Wavefront sensing (Shack-Hartmann wavefront sensor, wavefront reconstruction, wavefront-sensorless AO)
7. Wavefront correction (tip-tilt mirrors, deformable mirrors, piezoelectric effect, microelectromechanical systems, electrostatic actuation)
8. Simulation of adaptive optical systems (analytic vs. end-to-end modelling)
9. Propagation of laser beams through atmospheric turbulence (Gaussian beams, Rytov theory, scintillation index, beam wander)
10. Modelling of free-space optical communication systems (aperture averaging, mean signal-to-noise ratio, false-alarm rate and fade probability, bit error-rate)

The students will:

get familiar with Fourier description of imaging through aberrated optical systems and random media,

understand the description of aberrations through Zernike modes,

learn how to analytically compute the effects of turbulence on various optical observables such as image/beam motion, temporal power spectra, Zernike modes, scintillation, etc.,

understand the effect of noise on various quantities and metrics pertinent to the design of adaptive optical systems,

understand the advantages and disadvantages of various schemes for wavefront sensing and correction,

learn how to simulate and design simple adaptive optics systems.
