Abstract
The present invention relates to an optical device used as a driving aid. According to the invention, a lidar is formed by a sample of glass doped with erbium and pumped by a fraction of the light flux generated by a xenon discharge lamp with a concentrator. The unit is disposed in a headlamp or other light, optionally making use of their lighting means, and enables a receiver and circuitry generating navigational aid parameters to be activated.
