"Veiling glare" is a term that is used in the field of imaging system design. Technically, veiling glare is stray light that reaches the sensor plane of an imaging system, and causes a decrease in performance. While a full non-sequential analysis is needed to account for this phenomenon accurately, many optical imaging systems only require a first-cut look at forward scattering effects. This article shows how to make such a preliminary veiling glare measurement using tools that are already built into OpticStudio. This analysis requires a few minutes to perform and can lead to meaningful results without going into the full non-sequential analysis.
