    Abstract: A lidar device includes a light source configured to emit a laser pulse to an object, a light receiver configured to receive the laser pulse reflected by the object, a first periodic wave generator configured to generate a first periodic wave when the light source emits the laser pulse and generate a second periodic wave when the light source receives the laser pulse, and a first comparator configured to compare a phase of the first periodic wave and a phase of the second periodic wave to each other. The lidar device calculates a distance between the lidar device and the object based on a phase difference determined by the first comparator.

    Abstract: A method of acquiring distance information is provided. The method includes determining a projecting order of different projected lights to be sequentially projected onto an object, based on a position of the object and/or an external input, sequentially projecting the different projected lights onto the object in the determined projecting order, obtaining modulated reflected lights by modulating the reflected lights reflected by the object; and acquiring information about a distance between the device and the object based on the modulated reflected lights.
