rishikesh now introduces a stroboscope for printing and packaging,engineering industry,aerospace,turbines manufacturers,gas generators,power generators,motor manufacturers etc. for checking speed like RPM and HZ or frequency testing , vibration checking ,motions analyses,motion study etc.
If a rapidly rotating or oscillating object is illuminated always at same position with periodic flash lights it appears to stand still or to move in slow motion.
An object illuminated with flash light stroboscopes only appears to stand still, of the rate of speed and oscillation is in complete unison with the flash rates respect, if it is multiple of flash rates. This enables besides of the observation also exact no contact measurements.
A further possibility is the apparent slowing down a quick process by shifting flash rates to a certain amount in comparison with the real rate of speed. For example you get an apparent rate of speed of 6/min although the object is rotating with 3.000/min, if the flash rate are adjusted to 2.994 or 3.006 flashes/min.
