Пристрій оптоелектронного вимірювання тривалості світлового імпульсу

Abstract

The invention relates to measurement technique and can be used for measurement of lighting pulse duration.

The device for optoelectronic measurements of lighting pulse duration comprises a light source and are located an optical input along the strike of radiation, optical light guides, an optical output, a photodetector, a pulse counter. In the device there is a comparator unit, the output being connected with a pulse counter input and a time-delay line input, the output being connected with a light source input. The number of used light guides is two and the their length is selected so that owing to passing a light pulse along them the interconnection delay of one in relation to another makes a half time conforming to a threshold sensitivity.
