LiDAR（激光雷达）是一种遥感技术，通过将激光照射到物体上、然后用光电传感器捕捉反射回来的光来测量距离。近年来，在实现全自动驾驶汽车方面取得了巨大进展。LiDAR 具有高方位角分辨率，可以高精度找到周围车辆、行人、建筑物和其他物体的距离、形状和相对位置。这项技术在各种用途中的潜力引起了关注，包括 ADAS（高级驾驶辅助系统）和 AGV（自动导引车）。
滨松为 LiDAR 提供各种设备，包括作为光源的脉冲激光二极管，以及作为光电传感器的硅 APD、InGaAs APD 和多像素光子计数器。我们还为这些设备提供定制支持。
汽车用 LiDAR 主要采用直接 TOF 方法。此方法通过计算脉冲光从其光源行进、从物体反射并返回到传感器的时间长度来计算距离。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
