  • Patent number: 11313953
    Abstract: A distance measuring module includes a light emitter, a reflecting unit and a light receiver. The light emitter is configured to emit first light, wherein an object reflects the first light to form second light. The reflecting unit is configured to perform a movement to reflect the first light or the second light. The light receiver is configured to receive the second light for calculating a distance between the distance measuring module and the object. An axis is oriented at a first angle or a second angle with respect to a baseline when the reflecting unit is performing the movement. When the axis is oriented at the first angle, the first light is reflected to the object by the reflecting unit. When the axis is oriented at the second angle, the second light is reflected to the light receiver by the reflecting unit.
