Event synchronization for detector systems
View Patent ↗An event synchronizing apparatus E for an image intensification camera system C for gathering image data includes an image intensifier 348 for amplifying received light 312 . A relay optic assembly 316 is coupled between the image intensifier 348 and a digital image sensor 350 , such as a CMOS or CCD device. Digital logic 352 is used to process or output an image or related data 334 . An event detector 340 digitizes an input signal 342 from an illumination source 338 and generates an electrical output synchronization signal 346 in response to the input optical signal 342 . The image intensifier camera C derives imaging and control information for the synchronization signal.
1. An event synchronization apparatus for an image intensification camera system for gathering image data, the apparatus comprising:
an image intensifier means for amplifying received light;
a light transmitting assembly between the image intensifier and a digital image sensor to communicate the amplified received light from the image intensifier;
