1. A range estimation system for an optical sensing system, comprising:
an analog to digital converter (ADC) configured to generate a plurality of pulse samples based on a laser pulse returned from an object, wherein a waveform of the returned laser pulse is substantially triangular including a rising edge and a falling edge; and
a processor, configured to:
generate synthesized pulse samples on the substantially triangular waveform based on the pulse samples;
determine an arrival time of the returned laser pulse based on the ADC generated pulse samples and the synthesized pulse samples; and
estimate a range between the object and the optical sensing system based on the arrival time of the returned laser pulse.
