Abstract: Disclosed is a system including: a beam projector module comprising a light source and an optical device configured to diffuse light output from the light source to reduce an intensity of the light; an image sensor configured to receive reflected light formed by the light reflected from an object; and a signal processing device configured to measure a distance from the object by analyzing a characteristic of the reflected light, wherein the signal processing device operates the beam projector module in an eye-safety mode when the characteristic of the reflected light corresponds to a crack characteristic.
