  • Optical sensor-based position sensing of a radio frequency imaging device
    Patent number: 10444344
    Abstract: A method and apparatus for optical sensor-based position sensing are provided. In the method and apparatus, a first displacement is detected by a first optical position sensor and a second displacement is detected by a second optical position sensor of an optical position sensor assembly located on a radio frequency (RF) imaging device. A processor coupled to the optical position sensor assembly determines a position of the RF imaging device based at least in part on the detected first and second displacements. The processor determines a tilt of the RF imaging device based at least in part on the detected first and second displacements and associates, in a memory, the position and the tilt of the RF imaging device with data representing an RF image of a portion of a space disposed behind a surface captured by the RF imaging device.
