Abstract
Disclosed herein is a laser navigation module. A light source emits a laser beam. A housing includes an IR window and a transparent or semitransparent part. The IR window transmits or reflects the laser beam emitted from the light source, and also interrupts transmission of external visible rays. The transparent or semitransparent part allows light emitted in the housing to be transmitted out of the housing. An illuminator is installed in the housing. A light diffusion unit transmits the light emitted from the illuminator to the housing. The light diffusion unit has a re-reflective layer on a portion thereof facing the illuminator.
