The present invention relates to a thermal vision countermeasure system to enable concealment of objects from identification by thermal imaging night vision systems, including a screen made of thermoelectric modules, disposed between the target object and an IR detector. The screen, formed of at least one thermoelectric unit, is coupled to the target object, and the thermoelectric unit includes a Thermoelectric Cooler (TEC) module coupled to a plate formed of a material selected from aluminum, copper, or aluminum with copper, the plate being substantially larger than the TEC module.
