This article presents description and features of confocal 3D surface sensor which is based on the principle of diffraction-chromatic coding with subsequent RGB image processing for the purpose of terahertz spectroscopy applications. The main part of the sensor is a specially designed hybrid refractive-diffraction objective lens. RGB color image decomposition processing was done by regular color video camera.

Keywords:
attenuated total reflection spectroscopy, terahertz region, confocal 3D surface sensor, chromatic coding method.
