Inexpensive method for measuring shutter intervals of a motor driven camera

A household audio magnetic tape recorder can be used for recording pulses which are given by successive shots of a 35‐mm motor driven camera. The pulses transmitted from an X contact of the camera are recorded on a magnetic tape by the recorder through an electronic circuit. Time interval between su...

Description
Summary:A household audio magnetic tape recorder can be used for recording pulses which are given by successive shots of a 35‐mm motor driven camera. The pulses transmitted from an X contact of the camera are recorded on a magnetic tape by the recorder through an electronic circuit. Time interval between successively recorded pulses can be measured by use of an electronic counter. This simple method permits to record 20 pulses per second and measures the interval between any neighboring pulses.
