An optical control system is described which provides for more efficient operation of an optical device. The system is operable to provide an integrated output from the detection system. Accordingly, by controlling the operating time of the detection system of the optical device it is possible to match the dynamic range of the integrated output to the operational input range of an ADC means to provide a digital output value, thereby minimizing the quantization noise of the ADC means.
1. An optical control system comprising: a plurality of optical emitters and a detection system comprising a plurality of optical detectors, the optical emitters and the optical detectors defining therebetween an area of optical paths whereby the transmission of energy between an emitter and a detector may be modulated by an optical interaction occurring in the vicinity of said area, wherein the detection system comprises an integrator operable to receive and integrate an output of one or more of said optical detectors over time;a switch operable to cont...
