Abstract
A multi-channel light detection and ranging system includes a plurality of active channels, each comprising a photosensitive element arranged to be exposed to light and an analog front end circuit arranged for receiving a signal from the photosensitive element. A compensation channel comprises a compensation element and an analog front end circuit arranged for receiving signals from the compensation capacitor. A processing unit arranged for receiving signals from the active channels and the compensation channel, deriving at a compensation signal from the signal received from the compensation channel, and compensating for the crosstalk interference and/or the interference common to the analog front end circuits of the active channels, using the compensation signal.
