Embodiments of the present invention provide a distance measurement apparatus capable of improving time resolution, a time-to-digital converter, and a moving object. According to embodiments of the present invention, the distance measurement apparatus comprises: a light transceiver outputting light to an object by a start control signal and receiving the low frequency reflected from the object to convert the received light into an electric signal; a signal discriminator to generate a stop control signal; and a distance measurer calculating a flight time based on the start control signal and the stop control signal to measure a distance. 본 실시예들은 복수의 오실레이터들에 포함된 논리소자의 위치를 조절하여 복수의 오실레이터들의 클럭 폭을 조절함으로써, 시간 분해능을 향상시킬 수 있는 거리 측정 장치, 시간 디지털 변환기, 및 이동체를 제공한다.
