Abstract
Measurement and correlation of chamber pressure and projectile position d is accomplished using an array of phototransistors, illuminated by collimated light, which phototransistors are sequentially switched off due to the interruption of the collimated light by the passing projectile. Pulses generated thereby may be displayed on an oscilloscope along with the pressure-time trace.
