Measuring Perception of Line Separation at Varying Distances and Light Levels

[alex_boothby]

ive done a test were, i get someone to try and distinguish to lines that are 0.25mm apart from varying distances. then I am going to do some kind of calculation to tell me somthing (hopefully)

and i have done this experiement in different light levels, controlling the lux. and i have found brighter it is the wasier u can see, up to a point were no more is not any use.
