Example Using Reverse Ray Tracing

FIGURE 9.56 - The example in Diffracted orders for the example Grating Surface Property. Scattered rays have flux below the threshold so they are not traced.6 has been re-run with flux threshold lowered to 0.001 so that scattered rays are traced.

Example Using Reverse Ray Tracing

In this example we will start with the EllipticalReflector_Reverse.oml model and use reverse ray tracing.

First, open the EllipticalReflector_Reverse.omlexample model. In forward ray tracing, you would begin a surface source ray trace. Rays would be emitted from the Arc:Cyl surface, and rays would be collected at the Observation disk:Front surface (see Figure 9.57). Once the ray trace is completed, you would select the Observation disk:Front surface and display an Irradiance/Illuminance map using Analysis|Irradiance/Illuminance Maps. You could also display a Candela plot using Analysis|Candela plots, sort the rays using Analysis|Ray Sorting, display an incident ray table using Analysis|Incident Ray Table, or display ray histories using Analysis|Ray Histories.
