Laser diodes based absolute distance meter

Abstract : We present our first results in the realization of a laser diodes based telemeter. We aim at developing an air index compensated distance meter taking advantage of the dependence of the chromatic dispersion of the refractive index with air temperature. This will be realized by two simultaneous distance measurements at two different wavelengths: each measurement is based on the measurement of the phase accumulated by a radio wave propagated in air by an intensity modulated laser beam.
