Hugo in Hell
Sat, Apr 13, 2019Hell Schreiber
Hell schreiber is an early facsimile-like mode to transmit text/images over the air.
It was pointed out to me, that the ghost imaging technique could be applied to that
mode.
Ghost imaging projects a number of overlay patterns on an image and observes the amount of reflected light for each pattern. The pattern and image is a simple 8x1 raster moving through time, like a ticker.
The technique uses a (large) number of linear equations - Thus, it is ideal for an algorithm using Superposition.
Hell Sand, Hugo goes Excel
The Excel workbook calculates the observations (the encoder) and, reverse, solves the 8x1 image under noisy conditions (the decoder).
