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.

any one know anyhting else about this?

This is a very interesting experiment and it seems like you have put a lot of effort into it. It is great that you have considered the impact of both distance and light levels on the perception of line separation. It would be helpful to know more about the specific methods and calculations you used to measure this perception. Additionally, have you considered any other factors that may affect perception, such as age or visual acuity? It would also be interesting to see if there is a threshold distance or light level where the perception of line separation becomes too difficult, regardless of how bright or close the lines are. Overall, this is a well-designed experiment and I look forward to hearing more about your findings.
