Dual-Camera Cinematography for Studying Motion Transducer Output Characteristics
R. E. Herron, Joshua Weir · Perceptual and Motor Skills · 1968
A comparatively simple method of studying the relationship between a movement and the corresponding output of a motion transducer is described. A major feature of the method is the arrangement of two motion film cameras, one to film the movements and the other to film the electrical output record, so that the two camera originals can be synchronized and printed adjacently on the same 16-mm. film for frame-by-frame analysis.
