strobe pulse

strobe pulse

[′strōb ‚pəls]
(electronics)
Pulse of duration less than the time period of a recurrent phenomenon used for making a close investigation of that phenomenon; the frequency of the strobe pulse bears a simple relation to that of the phenomenon, and the relative timing is usually adjustable.

They usually have programmable "strobe pulse width," "setup time" and "hold time." The programmable setup time is when the slave is addressed/selected, but the strobe is not yet asserted.
In Polytec instruments, a pulsed LED is used as the stroboscope light source, the system's time resolution being determined by the width of the strobe pulse. By adjusting the repetition rate of the light pulse, in-plane motion can be frozen and examined.
It should be noted that template pulse mixing a signal with a gating pulse is not the same as summing a signal with a strobe pulse, and is also a much less sensitive detection operation.
The controllers set current intensity, pulse duration and delay of LED illuminators, offer filtering options for trigger signals, and synchronise strobe pulses with camera exposure to meet high-speed imaging demands.
