In this work, a study is made of the characteristics needed by emitters and detectors in order to build a sensor with the reflection of an infrared beam of light in external environments. The main problem to be solved is how to distinguish the reflection of the laser beam from radiation emitted by the sun ; the source from which most noise will come. Reducing the amount of noise captured can increase this signal noise relation. This is achieved by choosing the adequate wavelength and using filters ; or by increasing the power of the signal up to the limits permitted by international security regulations. After presenting the theory of the optimum working conditions, detection results obtained with various types of emitter and detectors are shown.
