<p>A low light level system is described wherein electrons, created by images directed to a photocathode (31), directly bombard active pixel sensors. Both the active pixel sensors and the output end of the photocathode are positioned in a vacuum envelop. The electron released from the photocathode (31), are directed to and at the active pixel sensors (32). The output of the active pixel sensor (32) detector may be stored, viewed or displayed at a remote location. Various applications are described including a novel camera.</p> |
