Abstract: In some examples, a method includes transmitting first light pulses according to a pre-determined pulse pattern in a first measurement period. The method also includes transmitting second light pulses according to the pre-determined pulse pattern in a second measurement period consecutive to the first measurement period, in which at least some of the first and second light pulses being unequally spaced in time across the first and second measurement periods. The method also includes receiving first detection signals representing detection of the first light pulses. The method also includes receiving second detection signals representing detection of the second light pulses. The method also includes providing a first light scattering measurement signal representing the first measurement period responsive to the first detection signals. The method also includes providing a second light scattering measurement signal representing the second measurement period responsive to the second detection signals.
