Abstract

Various types of time-of-flight (ToF) imagers have been developed to perform effectively in outdoor environments with strong ambient light. This paper presents a multi-zone light-tracing hybrid time-of-flight CMOS image sensor that combines advantages of scanning light sources and hybrid ToF measurements. The proposed sensor architecture and operation technique enable extended outdoor range measurements under strong ambient light conditions with reduced light-source power consumption.
