Ultra-rapid electronic camera

摘要

This invention is an ultra rapid digitally controlled electronic camera. It comprises a bilamellar optical image conversion tube having a photocathode, a narrow aperture for receiving photons from the object to be studied, a pair of electron accelerating electrodes, a quadrupolar spatial focusing lens, a temporal focusing lens and means for recording the image of the aperture to a screen. The camera also has electrical supply sources for the lenses and electrodes. The invention also has a pair of prefocusing temporal electrodes connected to an adjustable voltage source, a pair of acceleration electrodes parallel to the aperture, and two deflection plates connected to adjustable voltage sources. The camera has a control unit distant from the tube to control the regulation and measurement means for the source voltages situated near the tube. Its application is for the study of very rapid light phenomena.
