We propose colors light detection and ranging (LiDAR) using visible laser diodes (LD) of red, green, and blue (RGB) colors to identify colors as well as obtain position information of surrounding objects. To verify the principle, we performed round-trip time-of-flight (TOF) measurements by irradiating a target of different colors with pulsed light from a LD of RGB colors. It is clarified that accurate distance measurements of up to 12 m can be realized in any RGB LD, and the received signal in each LD has different intensity characteristics depending on the target color. From a judgment table created from reception intensity characteristics for three types of LD and seven types of color target, the color of each target is successfully identified.

我们提出了使用红色、绿色和蓝色 (RGB) 颜色的可见激光二极管 (LD) 来识别颜色以及获取周围物体的位置信息的彩色光检测和测距 (LiDAR)。为了验证原理，我们通过用来自 RGB 颜色 LD 的脉冲光照射不同颜色的目标来执行往返飞行时间 (TOF) 测量。澄清在任何RGB LD中都可以实现高达12 m的精确距离测量，并且每个LD中接收的信号根据目标颜色具有不同的强度特性。根据根据三种 LD 和七种颜色目标的接收强度特性创建的判断表，成功识别了每个目标的颜色。
