Embodiment Construction

[0029] Terminology: Fast axis, Slow axis Definition:

[0030] The fast axis of the semiconductor laser, also known as the vertical divergence angle θ⊥, is the angle at which the light-emitting band of the semiconductor laser opens in the direction perpendicular to the PN junction, generally around 15° to 40°. The slow axis of the semiconductor laser, also known as the horizontal divergence angle θ∥, is the angle between the light-emitting band of the semiconductor laser and the parallel direction of the PN junction, generally in the range of 6°--10°.

[0031] In order to make those skilled in the art understand more clearly, the specific structure of the illuminator involved in the present invention will be described below with a laser illuminator defined by specific quantified parameters.

[0032] Refer to the attached figure 2 and 3 , the semiconductor laser 11 is adapted to be embedded in the cooling fan 2 , and the power supply for both is supplied by the power supply c...

Abstract

The invention discloses a laser night vision auxiliary driving laser illuminator. The laser night vision auxiliary driving laser illuminator comprises a laser and a camera lens arranged on a laser emitting window. The laser night vision auxiliary driving laser illuminator is characterized in that the horizontal direction of laser light emitted by the laser is a slow axis, the vertical direction of the laser light emitted by the laser is a fast axis, correspondingly, the camera lens is provided with a fast axis lens set used for fast axis compressing and shaping, a slow axis lens set used for slow axis scattering and shaping, an emitted light angle control lens and a heterogeneity dodging plain film from back to front, and accordingly, long-emitted main light beams and short-emitted scattering auxiliary light beams are generated; the fast axis lens set and the emitted light angle control lens are respectively provided with a driving mechanism performing driving in the front and back direction. The laser night vision auxiliary driving laser illuminator is suitable for near-ground illuminating and long-distance illuminating.

Description

technical field [0001] The invention relates to a laser illuminator for driving with laser night vision, in particular to a laser illuminator in the field of driving with laser night vision. Background technique [0002] The existing night vision vehicle-assisted driving system imaging equipment mainly includes two types of infrared or low-light imaging auxiliary imaging. The infrared system is a passive thermal imaging system that detects the temperature and images the scene according to different temperatures. It can realize imaging that is not affected by the lights of oncoming vehicles at night. Thermal imaging assisted driving has disadvantages such as insufficient resolution, insufficient imaging details of road surface pits with little temperature difference, and high price. [0003] Low-illumination imaging equipment can image high-resolution and clear images of the road surface at night when there is weak light, but when encountering strong light on the opposite si...
