Dimple phenomena study by dichromatic colorimetric interferometry
Original language description
This study presents such a modification of colorimetric interferometry technique using dichromatic light source instead of white light and new refractive index correction algorithm combining Lorenz-Lorentz equation with density pressure equation and pressure distribution calculated from measured film thickness map. The efficiency of this technique has been tested through the observation of EHD film shapes under disc sliding conditions when a deep conical depression (dimple) appears within the contact area. Obtained results have proved that with the use of dichromatic colorimetric interferometry it is possible to obtain precise EHD film shapes for film thicknesses up to 1 500 nm with film thickness resolution approx. 1 nm and measurement accuracy 3 nm.
