In this technical publication, the process of modeling an arc lamp, using the Advanced Systems Analysis Program (ASAP®) by Breault Research Organization (BRO), is described.
ASAP is capable of creating a 3-dimensional (3D) volume-emitting source from a 2-dimensional (2D) CCD image of a plasma arc. ASAP converts the bitmapped (BMP) picture into its own display file, re-scales the image appropriately, and then produces the appropriate volume emitter by using an inverse Abel transform. The 3D source is rotationally symmetric and can be saved as a ray file. Any number of randomly distributed rays can be created. The source is placed inside an accurate CAD model of the lamp geometry, completing the realistic arc-lamp model.
