About a month ago we raised a question regarding displacement transducers
for Biomechanical investigations. We got surprisingly few responses,
perhaps due to our timing (Christmas holidays). The origininal
question follows, in case after the holydays there is more people out there
that can give us some more suggestion.
WE WELCOME ANY ADDITIONAL RESPONSES RELATED TO OUR QUESTION.
____________________ ORIGINAL QUESTION: ____________________
>I am looking for some displacement transducers to track plane motion with
>the following requirements:
>- range: 1 mmm;
>- accuracy: better than 1 micron;
>- able to measure motion along two directions in a plane (i.e. Eddie
>current and similar proximity transducers do not work).
>
>At the moment I could think only of using 2 extensometers or 2 LVDT to
>track the two displacement component.
>
>I would be interested either in some "mechanical" transducer or any
>non-contact transducer. Does anyone know of commercially available solution
>for this application?
>Any suggestion will be welcome. As usual, I'll post a list of the replies.
>
>Thanks you in advance and season greetings to everyone.
