Abstract
The present invention relates to a method for illuminating a first and at least a second light source in a light-emitting apparatus. This method comprises the acts of illuminating the first light source for a first period during which the first light source emits a plurality of light pulses, illuminating the second light source for a second period during which the second light source emits at least one light pulse, and repeating the illuminating acts. Furthermore, the present invention relates to a light-emitting apparatus for emitting light pulses and detecting these light pulses after they have been reflected or transmitted by a substance. This apparatus comprises a first light source for illuminating the substance with a plurality of light pulses for a first period, at least a second light source for illuminating the substance with at least one light pulse for a second period, at least one photodetector for detecting the light pulses after they have been reflected or transmitted by the substance, and a means for converting the detected light pulses into at least one reading.
