Abstract

Here we use a blank recordable compact disk as a diffractive device. A simple model for the disk grating is proposed. After the disk is properly cut, small pieces of it are completely immersed in the liquid of interest. Such a small piece is in fact a single-use reflective grating and we call it removable compact disk grating. Because it's very cheap and, for this reason, easy to remove it, the compact disk grating is a suitable device for contaminating fluids and particularly for human serum. The principle of the method allows to calculate the refractive index of human serum by measuring the angular displacement of the diffracted maxima, or by fringe counting in a grating interferometer.
