Stray light, also referred to as flare, is any light that reaches the focal plane via a non-design optical path. It can cause contrast loss (decrease in dynamic range), false features (seeing ghost images), and changes in color; all of which can degrade the quality of the images captured and even interfere with the ability to detect objects in the scene.
Imatest provides both software and hardware for stray light testing. Our solution includes the following:

Imatest version 22.2 introduced the stray light (flare) analysis. Import images into Imatest to run the analysis, where Imatest can process the images into normalized stray light metric images. Various information and summary statistics can be derived from the resulting metric images. Outputs include the metric images themselves, as well as plots, videos, and standard output files (e.g., JSON and CSV). The stray light module is available in both Master and IT on our software store page. See also our stray light documentation for more detail.
