Addvisia : modular multispectral imaging platform

An imager is an electronic component capable of detecting photons arriving on a pixel matrix. Depending on the technology, photons are captured at specific wavelengths. By coupling this component with an optical system and suitable electronic processing, an image is generated.

Common imagers are with rolling shutter: they capture and process sensor information line by line to form the image. In most cases, this is not a problem. However, in the case of a moving object, distorted images are generated. Global shutter sensors capture all sensor information at once. There is therefore no deformation after processing and reconstruction of the image.

On a ToF sensor, each pixel is able to measure the time of flight incident light has traveled between the camera and the object. More info about ToF on STMicroelectronics website and here.

Unlike frame-based sensors, event-based sensor doesn’t take frames. Instead of that, each pixel is independent and only record when it senses movement. Receptors collect the essential information and nothing else, 10 000 times a second, without needing to engage enormous amounts of brain power. More info on Prophesee website.

Like visible light, it is reflected or absorbed by an object to generate images with shadows and contrast. In SWIR images, water vapor, fog, and materials like silicon are good transmitters. One of the advantages of imaging technologies in the SWIR waveband is that they can “see” through glass. In terms of heat, SWIR imaging can “see” hotspots, typically between 500 °C and 3,000 °C. Versatility of SWIR waveband is making inroads into machine vision, where it provides inspection, sorting, and quality control capabilities. It can also be used to monitor temperature in the steel, glass, and other industries. Because SWIR imagers can “see” through smoke, haze, and fog, they are an excellent choice for surveillance cameras. More infos on Lynred website.

This waveband is the most widely used infrared band due to its excellent detection of most terrestrial objects. The maximum spectral luminance of bodies at ambient temperature is within the LWIR band. Applications : Uses for LWIR detection include defense, security, surveillance, thermography, temperature monitoring, predictive maintenance, gas leak detection, and more. This band is also used to enable smart building and advanced driver assistance systems (people counting, pedestrian detection) and for wildlife observation. More infos on Lynred website.

Totally ! Addvisia has been designed to help users discover what could be the benefits of imagers in given applications. We therefore work as much with companies discovering imagery as with experts wishing to go beyond the limits of the state of the art.

Addvisia allows you to quickly and easily test different types of imagers at once in your use cases, in order to orient you to solutions that are truly relevant to your needs.

The guarantee of confidentiality of the studies is governed by a confidentiality agreement (NDA) and by the Addvisia project’s chart.

Depending on your choice and the experimental conditions required, we can carry out the tests in our laboratory with our imaging infrastructures, at your location, or in another field test environment. In any case, our test team pilots the platform, carry out the camera settings and make the recordings in order to make the most of the technologies offered to you.

A test with the Addvisia platform is a rapid test with an empirical approach. Its price is therefore adapted to the exploratory phases of your project, so that you can have quick responses to intuitions without major expenditure. The price of the study is also influenced by the complexity of the case and potential mechanical adaptations that we could have to make, for example personalized mounting brackets.

It is the same project; Addvisia is the new name of System Lab. The rebirth through Addvisia was the opportunity for us to consolidate our offer, make it clearer and more visible for everyone.
