Abstract (en)

[origin: WO9935697A1] An infrared receiver having improved spatial coverage, comprising at least two mutually angularly spaced apart infrared diodes (10, 11) each having a respective axis of maximum sensitivity (12, 13) inclined at an acute angle ( theta ) to a common axis (15). The infrared diodes may be mounted on a respective surface of a polyhedral housing and may be discrete components or encapsulated in a common encapsulation. A method for increasing a relative sensitivity of an infrared receiver to a beam directed at an oblique angle to a reference direction, comprises sacrificing the sensitivity to a direct strike for the sake of the sensitivity to an oblique strike.
