Imaging system for a motor vehicle, to give the driver a view of the surrounding and especially in bad weather, has a feed of a drying agent between the lenses to prevent misting through moisture

摘要

The imaging system (1) for a vehicle, for observation around it, has an image sensor (3) and an optical system with a number of lenses (6A-6C) stacked behind each other within a tube (4) with spaces (7A-7C between them. Each intermediate space is connected to an exchangeable reservoir supply (8A-8C) of a drying agent of silica gel or zeolite, through a gas-permeable link (9A- 9C).
