Abstract

An information acquiring device includes a laser light source which emits light in a predetermined wavelength region; a projection lens which projects the light from the laser light source toward a targeted area; an image sensor which receives reflected light reflected from the targeted area to output a signal; and an imaging lens which guides the reflected light to the image sensor; a filter which transmits the light from the laser light source; and an actuator which inclines the filter. A filter controlling circuit inclines the filter in such a direction as to approximate a transmissive wavelength region of the filter to the wavelength region of the light from the laser light source.
