Claim 0:
1. A photodetection system comprising:
an optical scan device that includes:
an optical waveguide array, including a plurality of optical waveguides and;
a phase shifter array including a plurality of phase shifters connected separately to each of the plurality of optical waveguides;

a control circuit that controls a phase shift amount of each of the plurality of phase shifters and/or inputting of light to each of the plurality of phase shifters and thereby controls a direction and shape of the light beam that is emitted from the optical scan device;
a photodetector that detects the light beam reflected by a physical object; and
a signal processing circuit that generates distance distribution data on the basis of output from the photodetector.
