摘要：

A sensitive high T(c) superconducting bolometer has been fabricated on a 20-mu-m thick sapphire substrate with a YBCO thin film transition edge thermometer. Optical measurements with a He-Ne laser gave a noise equivalent power of 2.4.10(-11) W/Hz1/2 at 10 Hz and a responsivity of 17 V/W in good agreement with electrical bolometer measurements. Gold black smoke was then deposited on the back side of the assembled bolometer as an absorber. Spectral measurements on a fourier transform spectrometer show that the bolometer has useful sensitivity from visible wavelengths to beyond approximately 100mu-m. This performance is clearly superior to that of a commercial room temperature pyroelectric detector. Some improvement appears possible.
