Abstract
A distance detection device includes a light source, a light guiding component, an image sensor and a processor. The light guiding component is disposed adjacent to the light source and includes a discontinuous surface. The light guiding component is adapted to project a beam emitted from the light source onto an object to form an illuminating pattern spotted by the discontinuous surface. The image sensor is adapted to capture an image about the object. The processor is electrically connected with the image sensor and utilized to analyze position variation of a spot formed by the discontinuous surface within the image for determining a distance of the object.
