High-speed hologram camera developed

A high speed hologram camera, believed to be world class, was developed by Tianjin University scientists. It can shoot four photos in succession in transients of 2-100,000th of a second, with an interval of 5-millionth of a second between photos. At present, two photos are the international norm for such instruments, according to a university spokesman. The camera, developed by faculty members of the university's department of precision instruments, is designed to shoot transient processes like the vibration of lathe tools at high speed rotation. The components of the camera are all made in China, the spokesman said.
