Abstract: PURPOSE: A reflector mirror structure is provided to reduce etendue of light source and achieve improved light collection efficiency by arranging a retro reflector to an elliptical mirror. CONSTITUTION: A reflector mirror structure to be used in a projection engine, is characterized in that an elliptical mirror is installed such that a light source is located at a first focus, and a retro reflector is additionally arranged to the shaft of the elliptical mirror, so as to thereby improve light collection efficiency and reduce etendue of light source. The retro reflector is disposed in front of the light source so as to efficiently collect the light generated from the light source, and made of a semi-spherical mirror. Since the center of the retro reflector corresponds to the center of the light source, all the light colliding against the semi-spherical mirror returns to the light source.

Abstract: PURPOSE: An optical pickup is provided to easily detect an error through one photo diode and to improve the productivity by easily controlling an assembling. CONSTITUTION: A focusing is performed through one side of beam among the beam divided to tree beams, that is through only a +first beam. Therefore, a problem to sensitively enhance efficiency is occurred when a source of light(10), that is a laser diode, is changed its wavelength. To solve the problem, a first and a second patterns(32a,32b) having a supplementary relation are divided to detect an error through a sub beam, that is through the +first and the -first beams. A pattern is formed in a matrix structure so that the first and the second patterns take each half. The +first and the -first beams are spotted in the same photo diode(60). Thereby, the +first and the -first beams are collected in each half of one photo diode(60).
