Dear Friends,
I am currently looking for a cheap Laser Vibrometer to measure
ultrasonic vibrations upto ideally 2MHz. I know Polytech have a line of
laser vibrometers but unfortunately its out of my budget. Currently i
am using AE (acoustic emission sensor) to measure vibrations upto 2MHz
but due to the size of the sensor i am unable to attach it directly to
the test specimen which in my case is a steel rod embeded in concrete
and hence i am using an attachment fixed to the rod and the sensor
placed on this attachment.
Does anyone have any suggestion on any type of noncontact measurement
which operates in a wideband (upto 2MHz or more) such as noncontact
ultrasonic transducers or magnetostrictive sensors or EMATs? My budget
is approximately $2000.
Is there any Laser measurement system or something that can be
fabricated to measure these high and wideband frequencies using lasers?
I read in previous posts where someone mentioned that its quite easy to
fabricate a laser based vibration measurement system...but i am quite
sceptical on the accuracy.
Thanking you in advance for your time and any comments are much
appreciated,
best regards,
Ravi
