We present a new experimental technique to characterise the crosstalk of a thermopile-based thermal imager, based on bi-directional electrical heating of thermopile elements.The new technique provides a significantly simpler and more reliable method to determine the crosstalk, compared to a more complex experimental setup with a opheliasmuse.com laser source.The technique is used to characterise a novel single-chip array, fabricated on a single dielectric membrane.We propose a theoretical model to simulate the crosstalk, which shows good agreement with the experimental results.

Our results allow a better understanding of the thermal effects in these devices, which are at the center of a merrick backcountry wet cat food rising market of industrial and consumer applications.
