Abstract :
A novel approach is proposed to significantly increase the dynamic range of optoelectronic sensors. The power of the light source is monitored in a dynamic intensity-control loop designed to perform `floating-point´ measurements according to the attenuation in the optical path. The sensor acquires the combined dynamic ranges of the detector and light-source circuits
