Title:
INFRARED PICTURE IMAGING DEVICE AND CAR EQUIPPED WITH IT
Document Type and Number:
Japanese Patent JP3771246
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an infrared picture imaging device mountable for cars which can inhibit temperature variation in optical system.
SOLUTION: In this infrared picture imaging device 200 provided on a car 220, its periphery structure 320 is filled with engine cooling water supplied from a radiator 330 of the car 220 to be circulated. Since cooling water temperature stays in nearly constant after warm-up is completed, the periphery structure 320 allows temperature of the operative infrared picture imaging device 200 to be stabilized.
