Abstract
An imaging system includes a light-emitting device, an image sensor, and a control circuit. The light-emitting device includes a light source, a first waveguide that propagates light from the light source by means of total reflection, a second waveguide, and a first adjustment element. The control circuit causes the light source to repeatedly emit light pulses. Further, the control circuit causes at least some of the plurality of photo-detection cells to accumulate the signal charge in synchronization with the emission of the light pulses and thereby causes the image sensor to generate every first period of time a frame based on the signal charge thus accumulated. Furthermore, the control circuit causes the first adjustment element to change the direction of the emitted light from the second waveguide every second period of time that is shorter than or equal to half the first period of time.
