摘要： An optical tachometer sensor for providing output relating to rotational speed of an object. The sensor illuminates a reflective mark on the object with modulated light and focuses that light via a receiving lens arrangement onto a photoelectric sensor which provides signals to conditioning circuitry for controlling output. Lenses in the sensor also form a Galilean telescope or a terrestrial telescope to allow a user to boresight the sensor by viewing the reflective marker through the sensor. A beam splitter or "hot mirror" reverses the optical path of modulated rays generated by the device for forcusing on the photoelectric sensor, while allowing visible light to pass and be aligned by a divergent ocular lens. In the terrestrial telescope embodiment, a convergent inverting lens and ocular lens provide the image for the user and the photoelectric sensor may be located at the focal point of the objective lens or the inverting lens.
