Abstract
In an object movement measuring apparatus, a movement monitor detects the movement of an object under measurement to output a signal in synchronization with the movement, and the signal thus outputted is utilized to trigger the streak camera, so that the motion of an object moving at high-speed can be detected as a streak image.
Claims12
An object movement measuring apparatus, comprising:
- a pulse light source;
- an optical system for illuminating an object under measurement with a light beam emitted by said pulse light source;
- a streak tube having a photocathode and a pair of vertical deflection electrodes, for detecting a reflection light beam or a transmission light beam from said object and outputting a streak image output;
- a sweep signal generator for receiving a part of said light beam emitted by said pulse light source and providing a sweep signal to said pair of vertical deflection electrodes of said streak tube;
- an image-forming lens system for focusing said reflection light beam or said transmission light beam on said photocathode of said streak tube;
- a movement monitor for detecting movement of said object and producing a synchronizing signal which is synchronous with said movement;
- and
- a gate trigger signal generator for producing a sequential gate trigger signal to trigger said streak tube according to said synchronizing signals sent from said movement monitor.
