Abstract
A novel high-precision pulsed ranging method is developed. It involves preliminary transformation of photon detector signals (convolution), analog-to-digital sampling, software processing by deconvolution, digital filtering, pulse shape retrieving and pulse center determination. The method is effective for arbitrary pulse durations (shorter or larger than the sampling step) and is low sensitive to the shapes of the reflected pulses. Using 20 MHz/8bits ADC, an experimental timing accuracy is achieved of approximately 600 ps (approximately 10-2 times the ADC-sampling step) for single measurements and of approximately 30 - 50 ps (approximately 10-3 - 10-4 times the sampling step) in averaging regime.
