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： An encoder having a carrier that passes through an opening in a mounting body is disclosed. The carrier includes an encoding region having a plurality of clear and opaque regions, the carrier having first and second surfaces. The clear and opaque regions of the carrier pass through the opening in the mounting body when the carrier moves relative to the mounting body. A light emitter generates a light signal that passes through the carrier, the light emitter being located adjacent to the first side of the carrier and separated therefrom. A light reflector is attached to the mounting body at a position such that the light reflector directs the light signal through the second surface of the carrier where a photodetector measures light leaving the first surface of the carrier when one of the clear regions passes through the light signal.

摘要： A coding element such as a codewheel includes first and second surfaces that are configured with respect to each other and with respect to a light beam such that the light beam is reflected at the two surfaces using the optical phenomenon of total internal reflection. The coding element also includes a coding pattern that is aligned in an optical path of the light beam after the light beam has reflected off of both of the surfaces. A coding element with surfaces that reflect a light beam as a result of total internal reflection can be utilized in an encoding system that operates in transmission while the light source and the photodetector array are located on the same side of the coding element.

摘要： An encoder that includes a code strip and an emitter-detector module is disclosed. The code strip has alternating reflective and opaque stripes and an imaging element in contact with a surface of the code strip. The optical element directs light incident thereon to the code strip. The emitter-detector module includes a light source that generates light and directs a portion of the generated light to the imaging element. The emitter-detector module also includes a photodetector that generates a signal representing an intensity of light received by the photodetector. The imaging element images light reflected from the code strip onto the photodetector. The imaging element can include a lens having a planar surface in contact with the surface of the code strip. The imaging element can be structured such that the imaging element collimates light from the light source such that collimated light is incident on one of the reflective stripes.
