Abstract: The present invention refer to an optical device and data collecting system, more specifically to a system for collecting and analyzing the response of optical sensors, which use may be extended to a large number of devices and equipments with the purpose of analyzing objects in accordance with light reflected or generated thereby. The invention distinguishes from the prior art by having an extremely simple configuration which allows for the determination of specific features such as size, shape, color and speed among others, thus replacing conventional systems which, besides being expensive and complex, do not provide for a large assortment of information and are susceptible to errors and changes in view of environmental conditions.
