Abstract

An apparatus is described for making time-resolved spectrograms of single sparks or other short-time sources of light. Our adaptation of a conventional quartz spectrograph provides for sweeping the image of a selected region of the light source along the length of the slit by means of a rotating mirror. The time base can be made as short as 10 µsec. and time resolution of events in the source as brief as 0.5 µsec.
