In order to obtain extremely high range resolution in the time-of-flight(TOF) range imaging, jitter reduction induced in a trigger jitter of light source and gate drivers is indispensable. In this study, we have proposed dual-reference-plane-sampling (DRPS) for jitter reduction. The jitters induced in the light source and gate drivers are extracted using column-wise and row-wise reference pixels. In this paper, the effectiveness of DRPS is discussed with measurement results using a principle verifier.
