Disclosed is a contactless optical lens two-dimensional (2D) location detecting system comprising: a camera which comprises a barrel of ferrite material having at least one optical lens and a capturing device which captures an image entering through the barrel; a resonant circuit including inductors having coils wound around the barrel and capacitors; a sensor board which is placed at a location opposite to the camera and has an sensing area; and sensor coils which is placed within the sensing area and has a form of wound wires, the sensor coil which controls operation of a coli driver to emit a first electromagnetic wave, the resonant circuit which generates an energy by the first electromagnetic wave to generate energy and spontaneously emits a second electromagnetic wave by the generated energy, thereby detecting the location of at least one optical lens based on the voltage difference outputted from a comparator by the second electromagnetic wave. |
