Abstract
Optical detector with pulsed emission, particularly of the background suppression cell type, with means for rapid regulation of the emission current.When the voltage signal received V is located outside a regulation interval Z1, the emission current is multiplied or divided by a predetermined factor to bring the signal V rapidly within the interval Z1; when the signal V is within the interval Z1, the emission current is regulated by control means to attain a value corresponding to the adjustment of the signal V to a required value Vopt.
