Morphology
The meaning is directly compositional: 'retinal' = relating to the retina and 'scanning' = making a systematic scan, so a learner who knows both words will infer it means scanning of the retina (e.g., for identification). This adjective+noun combination is literal and follows common cross‑linguistic patterns, making the expression immediately understandable to learners who know the constituents.
Etymology
The noun retinal scanning comes from the image of a light or camera looking inside the eye. The machine scans the retina, the back of the eye, and reads its unique pattern like a fingerprint, so it is used to 'identify' people.
