The target of the project is a realisation of a laboratory instrument enabling us to measure surface roughness in a non-destructive way in the range from tens of nanometers to tens of micrometers without a priori assumptions concerning a character of the surface. The level of an information content is high (it is possible to determine all-important characteristics of the surface roughness) and it is possible to get results in the real time. The instrument proposed is a laser interference holographic mic roscope of an original construction with a laser light source tuneable in its wavelength (INNOVA Spectrum laser and the semiconductor laser, adapted version of which will be realised by the 2nd joint applicant workplace). In the output plane of the micro scope a hologram of the surface is created. This hologram is through a microobjective recorded by a digital camera. This procedure is performed consecutively with two selected wavelengths. A computer performs a reconstruction of the superposed holograms.
