measuring with optical displacement sensors


Thread Starter

Hi listers,
I'm looking for sensors which specifications are the following:
measuring range 200mm
resolution 0.1mm
updating frequency : 500 to 1000Hz
target material : wood boards
I have found this kind of sensors but best prices are about 1300 US$.
The technology is based on the reflexion of a laser beam on a CCD. I have to add an acquisition board to digitalize the sensor signal.
Are these kind of prices normal or do you know companies with more interesting products ?

A single laser beam and a matrix camera can give the same kind of measurements.
This technology seems cheaper but the measurement time is related to frame cycle. (20ms for CCIR format -> 50Hz updating frequency).

Is there any other technology cheaper than the above one?
Do you have some experience with this kind of measurements?
Thank you.

Hello....I am looking for the same thing as you are. Could you tell me some companies that supply or manufacture these kind of optical sensors ?Any luck with finding cheaper ones ?
Contact Sick Inc. They have the best on the market for lasers, as low as 3 mircons for Resolution and up to 250mm
