This paper describes the arrangement, the fabrication technique, and the re
sults of studying a 65-element uncooled membrane-type linear microbolometer
array. With a time constant of 3 ms, microbolometers with a temperature-se
nsitive VOx film and a constant bias current have a detectivity of up to 5
X 10(7) cm Hz(1/2)/W in the 8-12-mum region. (C) 2001 The Optical Society o
