residualscatter
Residualscatter is the portion of scattered light in an optical system that remains after the primary scattering components have been accounted for or removed. It manifests as diffuse background in images and spectra and can arise from multiple scattering, surface roughness, or scattering within the instrument. It is distinguished from stray light in that it is often intrinsic to the scene or optical path rather than external illumination.
Origins of residualscatter include multiple scattering events and small-angle scattering not captured by single-scattering models, scattering
Measurement and modeling of residualscatter involve subtracting a modeled primary signal or fitting a background component.
Applications and significance: In astronomy, residualscatter limits detection of faint structures around bright objects; in microscopy
Challenges and future directions: Distinguishing residualscatter from instrument noise remains challenging; advances include improved scattering models,
