LTcam Laser Thermography NDT

The LTcam is your new tool for Non Destructive Testing by Laser Thermography. Designed to detect surface and sub-surface defects on your materials (cracks, crevices, folds,…), the LTcam is an excellent alternative to traditional testing methods such as penetrant testing and magnetic particle inspection.

In few words

What is the LTcam?

The LTcam is the latest iteration of the Active Photothermal Camera (CPA), a laser thermography system developed by Intercontrôle. This new version has been developed in partnership with Edevis, a German company specialising in active thermography NDT, and Thermoconcept, its exclusive French distributor of active thermography NDT solutions.

As the CPA, the LTcam allows the detection of surface and underlying defects by exploiting the infrared emissivity of the inspected element resulting from the thermal excitation generated by the laser.

The energy source used is a class 4 heating laser with a maximum power of 200 W (previously 100 W). This laser, which is a point laser at the output of an optical fibre, is transformed into a laser line by means of microlenses. A clever system of mirrors and motors allows the horizontal and vertical movement of this line to scan the surface to be inspected. These last elements have been totally redesigned and improved for the LTcam, compared to the old version of the CPA, Athena.

The housing of the new LTcam has been designed for more modernity and modularity (modular handles, robot mounting, feet). Finally, a new software developed by Edevis, based on their standard DisplayImg 7 software, accompanies this new version of the CPA.

An association of 3 experts

The LTcam is the result of an intelligent fusion between the know-how of 3 experts

Intercontrôle

As a major partner in the project that led to the creation of the former CPA, Intercontrôle brings all its know-how, its experience and its knowledge to carry out laser thermography inspection in optimal conditions.

Edevis

As an integrator of Non Destructive Testing (NDT) solutions by active thermography, Edevis has coordinated and managed the development and improvement of the existing concept in close collaboration with the other partners. The LTcam was born from this fruitful collaboration.

Thermoconcept

As a recognised expert in NDT by active thermography, Thermoconcept enabled the 3 partners to be brought together. Today it also brings its experience in the commercial, marketing and communication fields to promote and market the LTcam solution.

      Step 1: Set-up

      Step 1

      Experimental set-up installation

      The operator sets the LTcam regarding the part to be inspected in a simple and quick way thanks to the pilot laser that simulates the line of the excitation laser. This allows him to define the size of the area to be inspected and thus obtain the best possible results in terms of detectability and sensitivity.

      Step 2

      Measurement configuration

      Thanks to the dedicated software provided by Edevis, the operator can easily configure his experience by defining the intensity of the laser excitation as well as its speed, area coverage and scanning direction (horizontal or vertical).

      Step 3

      Measurement perform

      The software automatically controls the synchronisation of the various system elements (infrared camera, laser, safety systems) and triggers the excitation according to the parameters provided by the operator. Then, the laser excites the surface to be inspected by scanning back and forth. At the same time, the infrared camera detects the temperature response of the workpiece surface.

      Step 4

      Analysis and results

      Following the acquisition, the software allows the operator a simplified processing of the images obtained thanks to the know-how of Edevis which has made the use of its software simple and ergonomic. The operator can then easily adjust his images and add precise measuring tools. An export of the images allows him to integrate them into his control report.
