Abstract

We fabricated a laser rangefinder for a long range distance measurement. The transmitter is our home-made laser with wavelength of 1535 nm and the peak power of 0.25 MW. The echo pulse laser signals are detected by an avalanche photodiode detector, then the signal is sent to analog to digital circuit board for signal processing. We developed an algorithms based on FPGA to de-noise and improve signal-to-noise ratio. The experimental result shows that our laser rangefinder is capable of measuring distance up to 20 km with false-alarm probability < 1% and the accuracy can reach less than 1 m by range-walk error correction.
