Abstract
The high level of expertise accumulated by Teledyne in designing ROIC for different spectral imaging sensors (from X-rays to far–infrared) enables the company to develop high performance thermal imaging sensors optimized for Size, Weight, Power and Cost (SWaP-C). The specific ROIC design discussed avoids almost any trade-off between scene dynamic range and NETD which is the main issue encountered by all other FPA suppliers. In this paper, we will show how to achieve a NETD of 50mK with a dynamic range higher than 1000°C without any FPA adjustment settings. Key characteristics of the sensitive material are described to highlight the capabilities of this technology for system operation: mainly the ease of operation due to fully digital ROIC and specific design will be demonstrated. Finally, we will see how all the previously mentioned key parameters are paving the way to affordable, powerful thermal imaging modules and cameras.
