摘要： An encode device, comprises a light source, an encode wheel and a light detector. A hollow dent is formed on the center part of the incident plane of the encode wheel. The inner circumference of the dent is provided with a ring-shaped lens such that the light impinging on the inner circumference of the dent is focused by the ring-shaped lens. The rim of the encode wheel is provided with a plurality of cylindrical lenses which are perpendicular to the ring-shaped lens such that the light leaving the encode wheel can be further focused. Therefore, the working beam projected toward the chip of the light detector has less interference.

摘要： A photo-detector based calculating means having a grating wheel with integrated lenses is provided. The photo-detector based calculating means having a grating wheel with integrated lenses includes a light source (1), a grating wheel (2), and a photo-detector (3), with the light emitted from the light source (1) impinging upon an input plane of the grating wheel (2). The photo-detector (3) has a set of photo-sensitive chips (31) to receive the working light beams emitted from the grating wheel (2). The input plane of the grating wheel (2) has a ring-shaped lens (24) to focus the light emitted from the light source (1). The output plane (23) of the grating wheel (2) has a plurality of tooth-shaped lenses (25), each projecting perpendicularly to the ring-shaped lens (24), which can focus the working beams after the working beams pass through the output plane (23), thus minimizing interference.
