ABSTRACT:
A pair of time to voltage converters consisting of a converter for measuring the pulse shape of an exciting light and a converter for measuring the luminous shape are simultaneously activated by a start pulse so that the measurement of the pulse shape of the exciting light and the measurement of the luminous shape can be carried out in parallel in order to reduce the measurement time and to measure the luminous lifetime of the sample with a high accuracy.
