Abstract
The present disclosure relates to a time-of-flight distance measuring device. The light source () includes a plurality of emitting portions (), each of which illuminates a respective one of the sub-regions (R, R). The light receiver () includes a plurality of receiving portions () corresponding to respective ones of the emitting portions (). The first controller () controls (i) a first emitting portion () to emit the emitted light including an N-order harmonic component of a fundamental frequency and (ii) a second emitting portion () to emit the emitted light including an M-order harmonic component. The second controller () controls a particular receiving portion () corresponding to the first emitting portion () to be sensible to the N-order M-order harmonic components. The multipath detector () detects occurrence of the multipath error when the particular receiving portion () senses both the N-order and M-order components.
