Abstract
Systems and apparatus for phase calibration in time-of-flight cameras. In particular, systems and methods are presented for a miniaturized cover design that at least partially encloses the time-of-flight (ToF) module. The geometry of the miniaturized design causes the signals reflected from the calibration device back to the ToF imager to have essentially the same time-of-flight. The design of the calibration device prevents the modulated emissions from leaking out to the environment.
