STMicroelectronics VL6180 飞行时间传感器，环境光传感器

STMicroelectronics VL6180 飞行时间传感器、环境光传感器&红外发射器是基于ST获得专利的 FlightSense ™技术的最新产品。这是一项突破性技术，实现对绝对距离的测量，且无需考虑目标反射率的大小。VL6180X 并非通过测量从物体反射回的光量来估测距离（精度受颜色和表面的影响很大），而是精确测量光照射到最近物体再反射回传感器所花的时间（飞行时间）。VL6180 在一个可回焊的现成三合一封装内，集成了一个红外发射器、一个距离传感器和一个环境光传感器，从而使 VL6180 易于集成，免去了终端产品制造商进行耗时又昂贵的光学及机械设计优化的负担。

Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL6180 precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight).

Combining an IR emitter, a range sensor and an ambient light sensor in a three-in-one ready-to-use reflowable package, the VL6180 is easy to integrate and saves the end-product makers the long and costly optical and mechanical design optimizations.
