Major Accomplishments:

  • Initiated field of laser beam shaping (1965)
  • Invented concept of the three-dimensional optical transfer function (1967)
  • Invented an “extrapolating pupil”, a pupil coating function that acts in real-time to extrapolate its aperture size, in principle producing unlimited resolution (1969)
  • Invented maximum entropy (MaxEnt) image restoration (1972)
  • Developing EPI (Extreme Physical Information) principle for finding the probability laws governing unknown physical systems (1989-present)
  • Based upon use of EPI, showed that in situ breast cancer should grow with time t as simply tg, with g the Fibonacci golden mean 1.618… (2002)
  • Based upon use of EPI, predicted that Fisher information, like Boltzmann entropy, changes monotonically with the time, giving a Fisher-based expression of the 2nd law of thermodynamics (1990).
  • Derived analytical expressions for the Weinberg-Salam angle and Cabibbo angle of particle physics (2002)
