Optical Profilometers
Camera models with profilometer extension
Laser triangulation is a non-contact distance measurement technique widely employed for surface inspection applications.
We've been working to develop a laser triangulation extension to provide our customers with a fast and reliable solution for their measurement and quality inspection issues. Our Optical Profilometer extension enhances the lasting and flexible platform of our standard cameras: you can get all the quality of Alkeria cameras, along with all brand-new functionalities!
Discover our new CELERA, CELERA One, and ARIA models featuring our new Profilometer extension.
How it works
In a laser triangulation measurement setup, a laser line is projected onto the entire surface of an object passing through the inspection area. Then, a CMOS camera placed at a predetermined angle acquires the shape of the laser line reflected from the object. From this shape, it is possible to measure the target profile.
Thanks to a dedicated algorithm and our state-of-the-art FPGA technology, Alkeria cameras can define and extract the line position in every column of the acquired frame with sub-pixel precision.
In particular, the Profilometer extension enables on-camera acceleration of the line position detection algorithm. Our cameras can extract and calculate profile coordinates by themselves, greatly reducing the amount of data sent through the USB3 interface.
In this way, users can easily reach the maximum sensor frame rate and collect only the data useful for the measurement.
Powerful platform
We decided to extend our standard area-scan cameras lineup by adding new models equipped with an optical profilometer feature: in this way, our users can take advantage of a reliable and proven system with the features and specifications of Alkeria standard cameras.
Our system relies on the well-known CELERA, CELERA One, and ARIA camera series. With up to 4112 pixels per profile resolution and an acquisition speed of up to 2.62 kHz (on 128 rows), you can easily find the perfect fit for every measurement application.
Check the Technical Specifications tab below to discover all our cameras' specifications.
Advanced interface
All of our cameras feature a USB3 interface. USB3 provides the most convenient and widespread interface, pushing speed performances to the top while powering directly the camera, thus eliminating the need for an external power supply.
Through a versatile I/O interface, it's possible to control external devices such as strobe lights, encoders, etc. Depending on the camera model, users can rely on 2 input lines with a direct encoder interface, 2 output lines, and 1 input/output (RS422, RS644 LVDS, LVTTL)*. Their multipurpose I/O connector provides user I/O, frame triggering, and a direct encoder interface.
