Abstract
A reflective photo-electric sensing system includes a transmitter for the transmission of light and a reflector for reflecting the light. The reflector being positioned in a far field. A light channeling device receives reflected light from the far field or from a near field and channels the received reflected light to a near field receiver or a far field receiver dependent on an angle of the received reflected light. An electrical signal is generated at the near field receiver or the far field receiver. A controller evaluates the electrical signal of the near field receiver and the electrical signal of the far field receiver and generates an actuation signal dependent on the evaluation.
