Abstract
A simple and energy-efficient detection device is disclosed, comprising an emitter configured to emit coherent electromagnetic radiation and an electronic control-unit connected to the emitter and configured to modulate the emitter to send electromagnetic radiation, receive electromagnetic radiation, generate an output signal based on a change in the property of the light emitter, wherein further at least two optical delay matters are connected to the emitter, the emitter is configured to emit electromagnetic radiation through the at least two optical delay matters, and the optical delay matters differ by their individual delay values.
