OPTICAL MODULE HAVING MULTIFOCAL OPTICAL SYSTEM FOR COVERING FAR RANGE AND NEAR RANGE IN ONE IMAGE Russian patent published in 2014 - IPC G02B23/10 G01N21/94 B60S1/08 

FIELD: physics, optics.

SUBSTANCE: optical module has a semiconductor element (4) with a surface which is sensitive to electromagnetic radiation and an objective lens (1) for projecting electromagnetic radiation onto the sensitive surface of the semiconductor element (4). An additional optical element (11) is placed in the space between the objective lens (1) and the sensitive surface of the semiconductor element (4). The objective lens (1) is positioned in such a manner and the thickness of the additional optical element (11) is such that an optical far range (8) is imaged by the additional optical element (11) in a first region of the sensitive surface of the semiconductor element (4) and an optical near range (9) is imaged in a second region of the visual field in which the additional optical element (11) is not located. In a vehicle, the optical module is placed in inside behind the windscreen (5) to record the outer space in the direction of movement.

EFFECT: high stability and reliability of the optical system of the sensor.
