CalibirTM an uncooled IR open platform designed for multipurpose applications

Abstract

Using a state of the art fully digital ROIC – topped with an uncooled bolometer - an infrared imaging platform has been developed to meet the expectations of more and more demanding applications. Indeed, cameras based on uncooled IR bolometers are becoming more popular and have been designed to fully meet the requirements of diverse markets, from machine vision applications to very lightweight, low power drones. Each application has its own unique requirements, which has led to specific interface developments (GigE with Precise Time Protocol / IEEE 1558 protocol, USB, MIPI CSI / DSI, and more) as well as developments in embedded image processing. In this paper, we will give an overview of the modular design process which has led to an easy to use modular interface. Of course, throughout this development real IR performance has to be taken into account - for example the capability to achieve a NETD of 50mK with a scene dynamic range higher than 1000°C without any adjustment settings; Image quality – with and without shutter – is also addressed paving the way to affordable, powerful thermal imaging modules and cameras.
