Abstract (en)

[origin: EP1557805A1] The device has an additional mirrors system with central, secondary and tertiary mirrors (25,27,29) focusing an infra-red radiation towards an infra-red sensor (15), where the radiation comes from detection or additional vision fields and does not pass via a lens system (19). The mirrors have different focal lengths and angular openings in their respective detection or vision fields.
