• The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize low-power consumption without giving up resolution or accuracy, even at relatively low speeds.
Quadrature-Phase Detection of Laser SMI Based on Square-Wave Modulation for Displacement Measurement
Abstract: We propose a new method called square-wave modulation quadrature separation (SWMQS) to reconstruct the displacement of the target in real time. A pair of quadrature laser self-mixing ...
Abstract: It is long believed that the phase information in a complex signal is lost in visible light communications (VLC) with intensity modulated and direct detection (IMDD). While Kramers- Kronig ...
