Triggered Rotating Mirror Camera It has been fitted to a standard rotating mirror camera converting it to a triggerable camera capable of being synchronised to an event, rather than vice versa. A rotational speed of 10,000 r.p.m. has been attained, giving, with the optical system on which the apparatus was tested, a picture—taking

A High Speed Mechanical Shutter Driven by a Gas Motorthe light lasts too long before or after the framing period. The problem is normally dealt with by the use of specially designed light sources with non—luminous objects. These have a square pulse output which corresponds with the camera framing time. Unfortunately such light sources are bulky, fragi

Synchroscan — A Technique for the Photography of Repetitive Picosecond Pulses the order of units of picoseconds. The oscillator is synchronised to the repetition frequency of these pulses, and by appropriate adjustment the pulses may be superimposed at the centre of the tube screen, and recorded photographically. A variation of the method, “Stroboscan”, is to set the frequen
