METHOD FOR SCANNING PHOTODIODES

摘要

A method for electronically scanning a photodiode array (23) that is sequentially illumi- nated by individual light beams (6) by way of shutter mechanism (17) that has opening and closing transition times during which each light beam is only partially projected onto the array. An integrating light projected on the respective photofliodes of the photodiode array (23) by each light beam over a predetermined period of time beginning after the opening transition time when the shutter mechanism (17) is fully open and end- ing prior to initiation of the closing transition time while the shutter mechanism (17) is still ful- ly open and producing electrical signals corre- sponding to the light integrated by the respective photodiodes over the predetermined period of time and storing the electrical signals for subse- quent use.
