Abstract

An infrared detecting apparatus includes at least one infrared-sensitive element. Focusing means focuses infrared energy from a first zone onto the at least one infrared-sensitive element. An opaque element including a throughhole is positioned such that infrared energy may pass through the throughhole from a second zone to the at least one infrared-sensitive element. The second zone is closer than the first zone to the at least one infrared-sensitive element.
