SWIR cameras for R&D applications

  • Playback time:5 mins read

Designed for scientific and R&D applications, short-wave infrared (SWIR) cameras are often based on an InGaAs detector, generally with VGA resolution (640 x 512) optimized for the 0.9-1.7 µm waveband. Infrared is itself divided into several sub-domains: the very near infrared, the...

Rainbow diffractometry to study the evaporation of drops from colloidal suspensions

  • Reading time:7 mins read

A rainbow is caused by the interaction of a beam of light with a drop of liquid. In the laboratory, rainbows formed by a laser beam illuminating a drop of liquid can be studied. By filming the rainbow, we can then study and extract physical information about the drop from this signal. In...

Optronic system characterization

  • Playback time:4 mins read

Optronic systems can be used in a wide variety of fields, including surveillance, defense, industry, food processing and healthcare. These systems need to be tested during design, manufacture, calibration and installation. It is therefore essential to characterize them in the laboratory. Introduction In this article, we discuss...
