ABSTRACT:
Two pairs of pyroelectric devices are each mounted on a cone-shaped substrate to precisely control their alignment. Each cone-shaped substrate is a part of a sensor module which also supports an attenuator, along with a transistor and a resistor chip associated with each pyroelectric device of the pair. The sensor module is provided with a silicon filter through which infrared radiation is transmitted to the pair of pyroelectric devices. Each module is mounted in an inner space formed by two hemispherical lenses which serve to direct light to the module. Two such hemispherical lens-sensor modules are provided in a precise optical arrangement designed to operate in conjunction with associated circuitry in order to detect infrared radiation from any of six distinguishable zones. Applications of such a device include for example cameras and air conditioning systems.
