CRYOGENIC BOLOMETER Russian patent published in 1996 - IPC

FIELD: measurement technology. SUBSTANCE: bolometer has heat-sensing element and heat-transfer fibre made of material whose power-temperature dependence of heat conductance at working temperature of bolometer has exponent lower than zero. Dynamic heat transfer from heat-sensing element of such bolometer is lower than static heat transfer value. This increases dynamic thermal resistance while desired thermal balance of bolometer is maintained thereby increasing temperature and voltage-watt sensitivity. EFFECT: improved sensitivity of bolometer. 2 dwg
