Reflecting mirror 301 opposite direction in the first direction is obliquely installed to the direction moving closer to the first array of source; Polaroid 302 is obliquely installed to the direction moving closer to the first array of source in the first direction. As the preferred mode of one, the light beam that first light source 101 of the present embodiment is launched angle of incidence on reflecting mirror 301 is 45 degree, the light beam that secondary light source 201 is launched angle of incidence on polaroid 302 is also 45 degree, angle between reflecting mirror 301 and polaroid 302 is 135 degree, thus reflecting mirror 301 is specifically configured to become 145 degree of angles with first direction, polaroid 302 is set to first direction in angle of 45 degrees.
The first light that definition is reflexed to polaroid 302 by reflecting mirror 301 is the first reference light.
Close in light unit 30 at one, it is the second reference light that reflecting mirror 301 makes with the setting of polaroid 302 to be overlapped with the second light reflected by polaroid 302 by the first light of polaroid 302 transmission, and by the optical axis coincidence of the first light of polaroid 302 transmission with the second light reflected by polaroid 302.
