Ever try to use a non-contact distance measurement sensor (or optical sensor) to measure the inside of a narrow hole or tube?
How about scanning undercuts or side walls of 3D objects?
If you have, you probably know that it is not an easy task and can be expensive and complicated. Typical triangulation-based sensors will certainly not capture these difficult shapes. Even collinear sensors won’t be able to measure the 90° angles and hidden surfaces completely.
Before you admit defeat and decide that there are some things that just can’t be measured, consider this:
Collinear technology such as Optimet’s conoscopic holography opens the door to many new ways to measure, that simply would not be possible with a non-collinear solution.
Optimet is announcing two new products which are good examples of the many solutions possible with collinear measurement sensors:
ConoPoint with Periscope
Optimet’s sensors are based on a unique technology for non-contact distance measurement called Conoscopic holography. This technology enables a collinear distance measurement, meaning the outgoing laser beam shares the same optical axis as the returned signal.
By using this unique property we can add on an accessory to the sensor which acts like a periscope, bending the laser emitted from the sensor by 90°). This allows you to insert the periscope’s tip into holes and measure their inner structure.
This becomes very useful when you need to measure diameters, steep angles and side walls of holes or pipes.
We can take this logic one step forward: what if instead of placing a mirror at 45° to the laser beam (creating a 90° angle when reflecting off the mirror) we use a rotating mirror which can give us more than one angle?
Well, great idea! That is why we created the ConoLine-100.
The ConoLine-100 contains the new ConoPoint-20 sensor and a rotating mirror, using the point measurement rate of 20 kHz to generate up to 100 lines per second.
By using a mirror we achieve two significant advantages:
Here are just two examples of scans that would not be possible without the ConoLine-100:
At Optimet, we’re ready for any challenge. We are confident in our technology and our ability to adapt our products to your measurement challenge.
