Vehicle laser radar sensor, has zero-cross comparator to compare light reception signals outputted from photoreceptive units with preset signal to output comparison signal, and integrator to integrate one-bit digital data for each unit

摘要

The sensor has a zero-cross comparator (95) to compare light reception signals outputted from photoreceptive units with a preset standard signal to output a comparison signal indicating two different states related to the comparison result. An integrator (77) converts the comparison signal into one-bit digital data and integrates the data for each unit. A sensor compares the integrated data with a preset integration standard value.
