hi.....
As a postgraduate student in the Department of Mechanical Engineering, I am interested to ask the following question : If we project a picture with a black and white background ( dark and bright ground ) on a screen by UV projector, what would happen when we put a radiometer in front of the projector’s light? (1) Does the UV light exist in the part of the picture which has dark background? (2) or the UV light in the dark background of the picture is less than the UV light in the bright background of the picture? (3) or the UV light remains the same over the entire picture?
Sincerely yours,
Nima Nouri
thanks
