METHOD OF TESTING PHOTOELECTRIC PARAMETERS OF PHOTOCELL UNIT

摘要

FIELD: electronics. SUBSTANCE: method comprises steps of applying illumination onto an active surface of all photocells in order to evaluate quality of separate photocells; then placing a member for differential illumination between the light source and active surface of the photocells; scanning the active surface of the photocells; measuring their output voltage; removing the light source; applying a bias voltage on each photocell, being tested, and measuring dark current, being occurred in the circuit. EFFECT: enhanced accuracy of parameter testing. 1 cl, 2 dwg
