Disclosed is a portable scanner, comprising: a light output unit from which light is emitted; a light emitting unit for generating a focus for the output light which is output from the light output unit and assigning an orientation for the output light; a light splitting unit located in front of the light emitting unit to guide the output light toward the front and a side; a first reflection unit located in front of the light splitting unit to reflect the output light guided through the light splitting unit toward an object to be measured which is disposed in the oral cavity of a patient; a second reflection unit disposed around the light splitting unit to reflect the reflective light, which is reflected from the object to be measured through the first reflection unit, or the output light, which is guided toward the side by the light splitting unit, rearwards; a phase modulation unit disposed behind the second reflection unit to vary a light travel distance from the light splitting unit; and an image information acquisition unit for receiving the light reflected through the phase modulation unit again and the light reflected from the object to be measured. |
