A CIRCUIT FOR AN OPTICAL SCATTER DETECTOR AND METHOD OF CONTROLLING AN OPTICAL SCATTER DETECTOR

摘要

A circuit for an optical scatter detector having a light source incorporated into a light source control circuit (10) arranged to illuminate a detector chamber (14). A light scatter detector (12) is coupled to a controller circuit (16) which is effective to control, via the light source control circuit (10), the light output from the source, in accordance with the detected scattered ligth detected by light scatter detector (12).
