Abstract
A motion or saturation determination apparatus () comprising: a light source configured to emit light and an optoelectronic device () configured to receive an electromagnetic signal and to translate the signal to a plurality of electrical output signals corresponding to a plurality of predetermined phase offset values in accordance with an indirect time of flight measurement technique. A signal processing circuit () of the apparatus () is configured to process the electrical output signals to calculate a plurality of measurement vectors derived from the plurality of electrical signals. The vectors are in respect of a plurality of frequencies and comprise a first measurement vector for a fundamental harmonic frequency and a second measurement vector for a non-fundamental frequency. The circuit () is configured to calculate a scalar relating a first amplitude of the first vector to a second amplitude of the second vector, and to use the scalar to identify motion or saturation in respect of the optoelectronic device ().
