Target

The target defines how the results are going to be interpreted in the feature viewer.

Description

The target is more or less acting like a sensor. You can choose from this section how the results are going to be interpreted and what pieces of information are going to be displayed in the feature viewer.

Target Type

The target type defines what kind of values/metrics will be available in the feature viewer. Two target types are available:

Intensity

With a Target Intensity, intensity values will be displayed on an angular grid in the feature viewer. It is often used when the area to light is defined angularly.



Note: Target Intensity is based on intensity sensor having an X As Meridian, Y As Parallel orientation (vertical poles). This matches to a SAE type A goniometer (horizontal rotation over elevation) used commonly in Automotive.

Illuminance

With a Target Illuminance, illuminance values will be displayed in the feature viewer. Illuminance target is often used when the area to light is located at a known distance from the source.



XML Template

If you want to verify that your current design passes regulation standards, you can input a XML Template corresponding to the regulation standard.

The XML template will be used by the Photometry tool simulation to generate the photometric preview displayed in the feature viewer, the HTML report and the XMP file of the selected element(s) of the feature.

You can find existing XML templates of regulation standards in the Ansys Optical Library.

For more information on the Photometry tool, refer to Understanding Display Properties.

Intensity result viewing direction

This parameter adjusts the viewing direction of the observer.

From source looking at sensor (Intensity/Illuminance target): The viewing direction of the observer is the same as the light direction emitted.
From sensor (Intensity/Illuminance target) looking at source: The viewing direction of the observer is in the opposite of the light direction.
