热能使红外探测器发生自激,使发射器失效或损坏和使电阻产生噪声。采用这种手提轻便型和可接近绝对零度的微型致冷装置,就可以减少上述这些毛病。选择这种装置要看器件的温度、热负载、可允许的振动和所需的效率而定。 Thermal energy causes self-excitation of the infrared detector, deactivating or damaging the transmitter and causing noise on the resistor. With this handy portable and close to zero absolute miniature refrigeration devices, you can reduce these problems. The choice of device depends on the device's temperature, thermal load, permissible vibration, and required efficiency.
