Abstract:
A time of flight sensor device is capable of extending its total sensing distance using multiple measuring sequences for each distance measuring operation. Such embodiments can execute two or more iterations of a measuring sequence, where the gating signal control sequence for each measuring sequence is offset in time relative to a previous sequence. This yields a greater number of sampling points within which a reflected pulse can be detected and measured, resulting in a total measurable time of flight range that is greater than a measuring operation that uses a fixed timing for the gating signals.
