Kind friends:
It occurs to me that stroboscopic tachometery represents a highly satisfactory solution to determination of rotor bearing condition (Re: Coolidge RA types) --- Moreover, owing to enhanced switching stability and favorable (i.e. compact) geometry, LED technology would seem a better choice than traditional ‘flash-tube’ systems…
Hence my questions:
1) Do ‘ultra bright’ white LEDs exhibit significant ‘after glow’? If yes, what is the antcipatable range in characteristics (i.e. luminance vs time following interruption) –- failing precise data - how do such LEDs compare to Xe 'photoflash tubes' in this regard?
2) Are such LEDs 'tolerant' of rapid switching?
Many advance thanks for any and all assistance!
Best regards
