The optical element includes a first surface and a second surface opposite to each other and perpendicular to a first axis, and has at least two light-passing regions. Light beams from an object to be positioned pass through the light-passing regions from the first surface to the second surface. The light sensor and the optical element are spaced by a predetermined distance on a direction of the first axis. The light sensor senses the light beams from the light-passing regions to generate at least two light-sensing signals. A distance between the object and the optical element is positively correlated to the predetermined distance. The processing unit receives the light-sensing signals and positions the object according to the light-sensing signals and the predetermined distance.

    摘要： The present invention relates to a capacitance sensing circuit with anti-EMI capability. A filter is coupled to a capacitor under test; receives a plurality of reference signals; and produces a first filter signal and a second filter signal. A difference circuit receives the first and second filter signals; eliminates the common-mode noise in the first and second filter signals; and produces a difference signal. The amplitude of the difference signal is related to the capacitance value of the capacitor under test. Thereby, the purpose of sensing capacitance can be achieved. In addition, by eliminating common-mode noise using the difference circuit, the anti-EMI capability can be achieved. Because the difference circuit can adjust the dynamic range of the output of the filter, the capacitance sensing circuit with anti-EMI capability can achieve capacitance sensing in few clock cycles.
