Latest Patents
John D. Rogers holds a patent for a laser photoelectric sensor. This invention utilizes a laser diode that emits laser light, which is then collimated into parallel rays using a collimating lens. The collimated beams can travel distances of 50 meters or more before being reflected back to a photoreceiver. A ball lens focuses the reflected light onto the photoreceiver, which is preferably a synchronous detector. This detector issues control pulses to a laser drive circuit, causing the laser diode to emit intermittent bursts of laser light. The synchronous detector compares the timing of the received light with the control pulses to distinguish between true reflected light and stray light. An intensity adjustment feature allows for the adjustment of laser light intensity based on the distance between the laser diode/photoreceiver and a reflector. This design accommodates distances of 1-70 meters without requiring lens modifications. Additionally, a reference voltage proportional to the intensity of the laser light is used in a gated feedback system for faster response times.
