A hologram is a three-dimensional image created by the interference of coherent light beams. The resulting interference pattern recorded on the photosensitive material contains all the information about the arrangement, intensity, directions and phases of the light waves reflected from the objects at the time of recording. The recorded interference fringes are an optical grating through which light is deflected from the initial direction and amplified in some directions by constructive interference, thus reproducing a highresolution image in three dimensions. In the process of making holograms, classical holography was replaced by computer generated holography, in which numerical methods simulate the physical basis of holography. Due to the specificity of information recording and the demanding production process, holograms have found their main application in protective printing. Holograms for this purpose are made in several ways (CtF printing, laser engraving, embossing, ...). In this work, the recording of transmission computer generated holograms on polycarbonate is demonstrated using laser engraving. For the purposes of this work, a fiber laser with a wavelength of 1064 nm and polycarbonate was used as the material on which the hologram was written. For the final result, an example document was created that contain several transmission computer generated holograms. In order to test the assumptions of quality printing, a set of samples was created that were used to calibrate the final process.
