摘要：
A small-area high-T(c) superconducting bolometer with a dense YBCO meander wire on a (100) Zr(Y)02 substrate has been tested at lambda = 1.5 mum using a diode laser as the radiation source. The infrared power absorbed by the bolometer was calibrated using a dc infrared substitution method. Responsivities of hundreds of V/W with a millisecond response time were obtained at a temperature of 86.5 K in the modulation frequency range of 10-3000 Hz. A minimum noise equivalent power of 6 X 10(-11) W/Hz1/2 was measured at 1000 Hz. The experimental results are compared with those obtained from a thermal analysis of the substrate-supported microbolometer. No nonbolometric effect was distinguished.
