Stray Light Analysis and Suppression of Panoramic Annular Lens
Acta Optica Sinica, 2013 A new stray light analysis method and some suppression principles of panoramic annular lens (PAL) are introduced in this paper. The proposed method is to find stray light paths which are caused by ray splitting on two refractive surfaces of the PAL block and then cut them off.

Guest Editorial: Stray Light and Its Suppression [PDF]
Optical Engineering, 1979 Stray light presents a continuing problem to the optical engineer. It reduces image contrast, introduces spurious signals, and in cases where a strong extraneous source is present, can completely mask the light from a weak object. Attempts to reduce or eliminate scattered light are often empirical and usually not very successful.

Stray light control for the space-agile optical system with pointing mirror
, 2023 The space-agile optical composite detection system with pointing mirror possesses flexible and fast response ability. Just like other space telescopes, if the stray light is not properly eliminated, it may result in a false response or noise flooding the
