Infrared Detection by Si‐Ti‐C‐O Fibers

摘要: Electrical resistivity at 20° to 90°C and infrared (IR) responses (thermal time constant responsivity of electrical resistance changes) were measured on Si-Ti-C-O fibers. The fibers showed negative temperature coefficient resistance-temperature characteristics, the thermistor B was 890 4760 K. A fast steady output (resistance change) observed in response IR radiation from a 600 K blackbody furnace. affected markedly by detector structure; thermal decreased with decreasing length fibers, increased number In an separate arrangement few (n=10) short (1 mm) low (80 Ω·cm), 3.5 ms 63 V/W obtained. suggests possibility detecting both stationary moving sources.
