    Abstract: A beam splitting module and a projector device using the same are provided. The beam splitting module comprises a projector, a first reflective mirror and a second reflective mirror. The projector projects a first split image, a second split image and a third split image. The first reflective mirror reflects the first split image to a real image forming plate to form a first projection image. The second reflective mirror reflects the second split image to the real image forming plate to form a second projection image. The third split image is projected on the real image forming plate through a space between the first reflective mirror and the second reflective mirror to form a third projection image.

    Abstract: An optical encoding device includes a light source module, an encoding disc, and a photodetector. The light source module emits a source beam. The encoding disc is disposed on a passing path of the source beam. The encoding disc has first diffracting patterns. The first diffracting patterns include a plurality of sets of first diffracting patterns arranged along a radial direction of the encoding disc. Each set of the first diffracting patterns includes a plurality kinds of first diffracting patterns having different pattern extending directions and different pattern periods. When the encoding disc is rotating, the first diffracting patterns in each set of first diffracting patterns enter the passing path of the source beam in sequence, to cause a diffraction and form diffracted beams having different angles. The photodetector receives the diffracted beams having the different angles.

    Abstract: An optical encoder includes a light emitting module, a positioning device and a light separating structure. The light emitting module emits a light beam illuminating an illumination area of the positioning device. The positioning device includes light penetrating areas arranged in a dislocation manner. The light penetrating areas sequentially move into the illumination area. The light separating structure is disposed in the path of the light beam. The positioning device is disposed between the light emitting module and the light separating structure. When part of the light beam penetrates one of these light penetrating areas and is transmitted to the light separating structure, the light separating structure transmits the light to a sensing area and forms at least one first positioning optical pattern. The distance between two first positioning optical patterns formed by two adjacent light penetrating areas is greater than the pitch between the two adjacent light penetrating areas.
