Study, design and validation of a TEC Controller inside a FPGA

The infrared cameras are used in more and more domains as they allow a new perspective on our environment. The development of sensors with a high precision requires adequate cooling to reduce to a minimum the impact of the thermal noise on the measurements. The objective of this work is to design an electronic circuit capable of regulating the power injected into a Peltier module in order to accurately control the temperature of an infrared sensor. The main constraint of this work is the use of a FPGA as the heart of the regulating loop. This work covers all the steps from the discovery of the infrared sensors and the Peltier effect to the validation of the complete system, with the theoretical study of such a system and the design of a PCB as middle steps.
