Paper Abstract

The goal of this paper is to construct an irradiance simulation at an image. We will demonstrate a software method written by Al Greynolds for passing bitmap images through a lens system and directly viewing the changes to the image caused by the lens itself, sources outside the field of view, or defects in manufacture. The routine calls the emitting data command and is a new feature in ASAP 6.0 from Breault Research Organization. It is another way to evaluate a lens system and see the effects of irradiance modeling and more. The dynamic range covered by this simulation is not limited to 1 bit, 8 bit or 24 bit images. The distribution file is based on the full floating point precision of the computer and accurate to 7 significant digits. The method will accommodate any dynamic range the user wishes.
