Description
Technical field
The utility model relates to a kind of optical mirror plane, particularly a kind of cylindrical mirror assembly for Radar for vehicle sensor.
Background technology
Optical element has now been widely used in the fields such as imaging, communication, medical treatment.Cylindrical mirror is mainly used in and changes over picture size, for example a some hot spot is changed to spot into a line, or in the situation that not changing image width degree, change the height of picture, be applied in line detector illumination, bar code scanning, holographic illumination, optical information processing, computing machine, Laser emission etc., cylindrical lens also has a wide range of applications in Radar for vehicle sensor.
Along with socioeconomic development, the popularity rate of automobile is more and more higher, so that often occurs the social concern that traffic congestion and traffic hazard take place frequently, and driver on the way needs more notice during running automobile, and this has increased extra mental burden to driver.Along with the raising of social development and people's moral civilization, people not only need to have considered driver and passenger's security for the concern of vehicle safety, meanwhile, also will consider other people safety on road.Therefore, the safety equipment of automobile, from the progress of tire and brake technique, turn to optoelectronic areas, as the automobile assistant driving system of generally using now, i.e. flexible car radar sensor.
Motor vehicles radar sensor belongs to the DAS (Driver Assistant System) of automobile, for the warning of vehicular safety distance and the control of system, and for finding the position at other vehicles of this vehicle periphery, remind the potential dangerous situation of driver, for vehicle can provide basic security function, its final goal is for driver provides information and delivers under special circumstances the automatic control authority of vehicle, thus safety that can underwriter's car.
Current car radar mainly comprises ultrasonic radar, microwave radar, laser radar, wherein, ultrasonic radar is outwards to launch ultrasound wave with certain angle, when ultrasound wave runs into object, is reflected back, and by receiving trap, according to the Time Calculation of ultrasonic propagation, goes out object spacing.Yet ultrasound wave is severe by propagation in atmosphere decay, is generally all no more than ten meters during application; Microwave radar transmitting millimeter wave active probe, although it can realize long-range detection, is mainly used for the measurement of object speed, more difficult accurately definite to object distance and position; Vehicle laser radar overcomes that other distance by radar is near, the shortcoming of low precision, by the optimal selection that is automobile assistant driving system.
The advantage that is used for the radar sensor use cylindrical lens of motor vehicles is the more favourable damping characteristic with Minimal energy loss, and cylindrical lens can be used as the high-frequency model of the bearing antenna element of coverture or antenna house at one time.Therefore, the utility model is provided for the cylindrical mirror assembly of Radar for vehicle sensor.
