Development of a Reference Device for the Calibration of Optical One-Shot Time-Interval Measurements

This paper presents the development of a device that creates two or more light pulses with precision time delay in range from microseconds to several seconds and for purpose calibration velocity detonation (VOD) measurement instruments. The was assembled, programmed, tested functionality. Measurements were conducted using reference counter. First, OCXO (oven-controlled crystal oscillator) used as clock source. For verification programmed subroutines, counter oscillator output port source signal microcontroller. enabled cancellation possible errors. had be converted an AC sine positive values only clamper circuit. By proposed solution, calculable standard between achieved. According obtained results, this can calibrate field devices VOD measurements explosives some other use where records interval multiple pulses. enables confidence faster recognition instrument drift increases quality measurement.
