The invention provides vehicle window glass, an information acquisition system and a vehicle. Wherein the window glass is provided with an information acquisition area, the information acquisition area is provided with a nano anti-reflection layer, and incident light penetrates through the information acquisition area and the nano anti-reflection layer to form first refracted light and second refracted light; the nano anti-reflection layer comprises a plurality of nano cones, and the plurality of nano cones are periodically arranged; and when the incident angle theta of the incident light is 45-75 degrees, the ratio of the transmittance of the first refracted light to the transmittance of the second refracted light is a main-secondary image transmittance ratio Cr12, and Cr12 is greater than or equal to 1000. According to the invention, the information acquisition device can obtain more accurate and clearer images.
本申请提供车窗玻璃、信息采集系统及车辆。其中,车窗玻璃具有信息采集区,信息采集区设置有纳米减反层,入射光穿过信息采集区和纳米减反层形成第一折射光和第二折射光;纳米减反层包括多个纳米锥,多个纳米锥呈周期性排列;在入射光的入射角θ为45°~75°时,第一折射光的透过率和第二折射光的透过率的比值为主副像透过比Cr12,Cr12≥1000。本申请能够使信息采集装置获取更加准确清晰的图像。
