We investigate both theoretically and experimentally wavelength division multiplexed confocal imaging by using white light supercontinuum. We show that with the optimized pinhole diameter an axial resolution of 0.75 μm and detection efficiency of 80% can be achieved. In addition, we applied the axial WDM confocal system to 3D surface measurement and the result agreed well with that measured by commercially available surface profilometer. The measured sensitivity of the system is 3.25 nm. Finally, we demonstrated lateral confocal imaging by using supercontinuum. An effective lateral scanning range of 130 μm was obtained.
