A Low-Cost Single-Pixel Thermographic Camera
Abstract
A working prototype of single-pixel thermographic camera which can be built for 100 Euros is presented. It is based on a pyrometer's sensor (thermopile with optics) and two mirrors mounted on servos to scan horizontally and vertically. Thanks to simple yet powerful filtering, the measurement proceeds at a speed of 5 ms per pixel even though the sensor has an actual response time of t90 ~60 ms. The scan for the resulting sharp image of 80x80 pixels takes one minute. We discuss further improvements to create a product suitable for facade thermography.
