An elevator associated within a hoistway and having a speed and position detection system. The elevator may include an elevator component associated within the hoistway, an optical sensor associated within the hoistway, an object associated within the hoistway in such a manner to be aligned in a path of the optical sensor, and a processor operatively coupled to the optical sensor. The optical sensor may be capable of emitting a signal and receiving a reflected signal of the emitted signal. The object may have surface features that may reflect the signal. The processor may be capable of processing the reflected signal to provide an output indicative of a speed and position of the elevator component. |
