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 a fast and reliable solution for their measurement and quality inspection issues. Our Optical Profilometer extension enhances the robust 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 with 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 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 optical profilometer feature: 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 CELERA, CELERA One and ARIA well-known camera series: with up to 4112 pixels per profile resolution and an acquisition speed up to 2.62 kHz (on 128 rows), you can easily find the perfect fit for every measurement application.

Advanced interface

All of our cameras features USB3 interface. USB3 provides the most cost effective and widespread interface, pushing speed performances at the top. Then, they are powered directly by the USB3 bus, thus eliminating the need for external power adapters.
Through a versatile I/O interface it's possible to control external devices such as strobe lights, encoders, etc. Depending on camera model, users can rely on 2 input lines with 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 direct encoder interface.

Drivers and software

An easy-to-use set of software API is available, which allows developers to quickly produce fast and clean code both on Windows and Linux, supporting all major programming languages, such as Python, C#, VB, C++ in Visual Studio or QT environment.
Our Software Development Kit provided together with the cameras, is fully compatible with Cognex VisionPro, MVTech Halcon, NI LabView and other major machine vision software for industrial application.
