Title:
LIGHT DETECTION AND RANGING SYSTEM
Document Type and Number:
Japanese Patent JP2018119954
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-channel light detection and ranging system capable of compensating for crosstalk occurring between active channels.SOLUTION: A system comprises a plurality of active channels, each comprising a photosensitive element 301 arranged to be exposed to light and an analog front end circuit arranged to receive a signal from the photosensitive element. A compensation element 307 is electrically connected to a network 302 shared with the photosensitive elements and to the analog front end circuit of at least one compensation channel. A processing unit 308 is configured to receive signals from the active channels and at least one compensation channel, derive at least one compensation signal from the signal received from the compensation channel, and compensate for crosstalk interference and/or the interference 311 common to the analog front end circuits of the active channels using the compensation signal.SELECTED DRAWING: Figure 2
