Abstract

This paper describes development of versatile one-dimensional high-speed video recording camera. It consists of linear-image sensor, frame memory and personal computer. This linear-image sensor scans object image one-dimensionally at the rate of 2MHz(maximum). At the maximum speed, sampling clock is 2.048 MHz, so shortest sampling period between line-scannings is 250 micro seconds. This is not so high speed compared with traditional streak camera. But resulting images can be digitized and stored in the memory. Therefore various image-analysis can be performed with personal computer. Experiment was performed to test this video-recording camera. The object was free-fall of a steel ball, which diameter was 30mm. The video-camera was operated at 512KHz to 2.048MHz. The resultant trajectory stored on frame-memory was time-displacement characteristic of object. In addition movement of blades of focal-plane shutter were recorded and analyzed.
