A 'Phase-Triggering'
Strobe Light. This type of strobe light differs in two ways from a conventional,
hand held strobe light:
-
It either feeds
frequency information (its flash rate) into the analyzer or has its flash
rate set by the analyzer.
-
It can be triggered
by a vibration signal from the analyzer.
-
A Photoelectric
Eye (or related mechanism that provides a 1x rpm pulse from the shaft).
