    摘要： An Enhanced Reflective Optical Encoder (“EROE”) having an emitter module for transmitting emitted optical radiation to an encoded media and a detector module for receiving reflected optical radiation from the encoded media. The EROE may include a transmissive layer covering both the emitter module and the detector module, and an optical isolation element located within the transmissive layer and located between the emitter module and the detector module. The optical isolation element reduces undesired optical radiation transmitted from the emitter module to the detector module, where the undesired optical radiation is a portion of the emitted optical radiation.

    摘要： An optical encoder includes an emitter, a first lens, a detector, a second lens, and a protrusion. The emitter emits light which is directed by the first lens to a code scale for reflection. The reflected light is directed by the second lens to the detector. The detector detects the reflected light from the code scale. The protrusion is between the first lens and the second lens. The protrusion defines at least one surface that refracts stray light from the emitter away from the detector. Accordingly, the stray light does not reach the detector; thus the detector can operate more effectively.

    摘要： A reflection-based optical encoding apparatus for the detection of position and/or motion of a mechanical device includes an encoding medium having at least a first reflective portion, and an encoder housing having a light-emitting source and a light-detecting sensor embedded within, the encoder housing being placed in proximity to the encoding medium such that a functional light path can be established from the light-emitting source to the light-detecting sensor via the first reflective portion of the encoding medium. The encoder housing includes a first flat facet positioned between the light-emitting source and the encoding medium, the first flat facet having a first angle relative to a common geometric plane such that light passing from the light-emitting source to the encoding medium is refracted along a first angled path in a manner that the refracted light strikes a desired location of the encoding medium.
