Simulating MT images (notes from Feb 12 meeting)

##
Randomly place emitters

###
using MT lattice

##
Each emitter produces airy disc in image plane

###
All air discs add up to form final probability density function for photon arrivals

##
Single-photon simulation

###
PDF in image plane can be used to randomly land photons

###
two random numbers per photon

###
double-precision number for photon position is converted into pixel location

###
All pixels are 16-bit (or maybe even double-precision) so you can count all photons without saturating

###
Starter-project for this method

##
Poisson (Gaussian) approx method

###
Actual average number of photons in an image is somehow estimated (from real data, perhaps)

###
Predict photons in oversampled (10x e.g.) image

###
Convert oversampled image to 1x version
