Abstract:

Structurally simple low-temperature dashed test objects (miras) with elements at temperatures lower than ambient are presented. These devices are based on thermoelectric elements (Peltier modules) with interchangeable thermal-insulating substrates mounted on them. The substrates have rectangular openings and heat-emitting conducting layers applied to the surface. Experimental thermograms of the models of test-objects are presented. The proposed devices are designed to align thermal imaging systems. They enhance the possibilities of investigating such systems and can be applied either separately or within infrared collimators.

Keywords:

low-temperature test objects, thermoelectric element (Peltier module), heat-emitting conducting surface, thermal-insulating layer, thermogram, profile of temperature distribution, thermal imaging systems alignment and investigation
