Abstract
A method for electronically scanning a photodiode array that is sequentially illuminated by individual light beams by way of a shutter mechanism 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 photodiodes of the photodiode array by each light beam over a predetermined period of time beginning after the opening transition time when the shutter mechanism is fully open and ending prior to initiation of the closing transition time while the shutter mechanism is still fully open and producing electrical signals corresponding to the light integrated by the respective photodiodes over the predetermined period of time and storing the electrical signals for subsequent use.
