Thermal imaging vs. thermography

We create experiences through renderings

Thermal image

Even if you don't see it, there it is!

The obtaining of thermal images is a technique used to highlight the characteristics of the elements to be inspected.

Like conventional cameras operating in the visible spectrum, these devices capture electromagnetic radiation from the IR spectrum, either from the same radiation emitted by the part or reflected from illuminators operating in a specific IR band.

To the values obtained, pseudo-colour representations or data to image conversions are applied in order to process them with artificial vision techniques.

Thermography

In addition to obtaining thermal images, thermography is the technique for measuring temperature from the radiometric values obtained by the acquisition devices.

The equipment is calibrated and certified in the laboratory with black calibration bodies at different operating temperatures.

The Infrared Spectrum

Making the invisible visible!

The band of the Infrared spectrum is a much wider band than the visible one, and with it different information is obtained depending on the wavelength where one works.

NIR

Near Infrared.

Conventional monochrome cameras with an increased sensitivity can capture NIR information.

Between 750 and 1400nm.

SWIR

Short Wave Infrared.

Other materials in the sensors, other than silicon, are already needed for data capture, such as InGaAs.

Wavelengths between 1.4 and 3um.

MWIR

Medium Wave Infrared.

They provide very extensive information and are used in applications such as gas analysis.

Wavelengths between 3 and 8um.

LWIR

Long Wave Infrared.

Microbolometer sensors are used to capture this radiation, and are precisely calibrated with black bodies for accurate temperature measurement.

Wavelengths between 8 and 15um.

IR Cameras

IR cameras are used for thermal imaging and temperature measurement by thermography.

Depending on the characteristics of the sensor, such as construction material or filters, they allow us to obtain the information of the infrared spectrum we want, from near infrared to long wave infrared.

Custom software development

Temperature measurement

Angular and distance corrections, emissivity maps, analysis by region of interest or compliance rates are only possible using powerful measurement algorithms developed and optimized for each need.

Custom HMI

We carry out a software analysis according to the specifications and needs of the client, developing operating environments according to usability, design and features required for each application.

Data storage

The data obtained and calculated are stored, in cycle, by means of an efficient database management. Traceability of images according to results obtained and history of reprocessable data.

Image processing

Inspection and control of defects by means of machine vision from the information obtained from the capture equipment. Image conversions for fast processing within the most demanding cycle times.
