PULSE SIGNAL PROCESSING APPARATUS, PULSE SIGNAL PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a distance measuring apparatus using pulse laser light allowing a wide measurement range and high-speed processing. SOLUTION: An object is irradiated with pulse light. Its reflected pulse light is received by a light receiving element. Its output is amplified by a synchronizing amplifier. Sampling data with a damped oscillation waveform responding to the reflected pulse light outputted from the synchronizing amplifier is added with one period shifted. Enhancement processing for a wave height value using the periodicity of the damped oscillation waveform responding to a pulse signal is thereby performed, improving the detection sensitivity for the reflected pulse light.
