Abstract

A vision system (1) for a motor vehicle (100) comprises a light beam generation part (2) adapted to generate at least one light beam (3, 3a, 3b) directed to a scanned surface (4) in the environment (5) of the vehicle; at least one light deflection device (6) comprising an array of light deflection elements (7), wherein the orientation of each light deflection element (7) is switchable between at least a first orientation and a second orientation, to redirect light which is incident on said light deflection element (7) from the scanned surface (4) in at least a first deflection direction (9) corresponding to the first orientation or a second deflection direction (17) corresponding to the second orientation; a plurality of light sensing devices (8a, 8b) adapted to sense light beam portions (18a, 18b) which are redirected from the at least one light deflection device (6) in said first and/or second deflection direction (9, 17) and incident on light sensitive surfaces of said light sensing devices (8a, 8b); a plurality of lens systems (11a, 11b) adapted to focus different reflected light beams (16a, 16b) from the scanned surface (4) to the light deflection device (6), wherein the first lens system (11a) is arranged to observe a first portion (4a) of the scanned surface (4) and the second lens system (11b) is arranged to observe a second portion (4b) of the scanned surface (4) that differs from the first scanned surface portion (4a); and a data processing device (19). The vision system (1) is characterized in that the number of light deflection devices (6) is smaller than the number of light sensing devices (8a, 8b); each of the first lens system (11a) and the second lens system (11b) is arranged to focus a corresponding reflected light beam (16a, 16b) from the scanned surface (4) to the light deflection device (6); and wherein light beams (13a, 13b) incident on the same light deflection device (6) and corresponding to said reflected light beams (16a, 16b) are directed to different light sensing devices (8a, 8b).
