Abstract:
1. A method for capturing an image, comprising: transmitting a disable signal to disable a bias light of a camera at a time prior to transmission of radiation; transmitting a first vertical synchronization pulse comprising an instruction to disable an electron beam of the camera; detecting commencement of the transmission of radiation after transmitting the first vertical synchronization pulse and prior to transmitting a next vertical synchronization pulse; after detecting the commencement and prior to transmitting the next vertical synchronization pulse, operating the electron beam to acquire an image during the transmission of the radiation and during disabling of the bias light, the acquired image representing first radiation received by the camera after the commencement and prior to transmission of the next vertical synchronization pulse; transmitting the next vertical synchronization pulse; and disabling the electron beam in response to the next vertical synchronization pulse.
