“…It allows the design of unique three-dimensional amplitude and phase elds that can expand the variety of holographic elements. Today, it is known about its application in microscopy [6], quantitative phase imaging [7], tracking of particles motion [8], measurement of gases or liquids ow in three-dimensional space [9], volume visualization of biological objects [10], information encryption [11,12]. However, with all the advantages of numerical methods, the recording time of single hologram is quite long, and the process itself is much complicated since some requirements should be met.…”

In this paper, we present two approaches for recording a quasi-hologram on the steel surface by femtosecond laser pulses. The recording process is done by rotating the polarization of the laser beam by a half-wave plate or a spatial light modulator (SLM), so we can control the spatial orientation of the formed laser-induced periodic surface structures (LIPSS). Two different approaches are shown, which use vector and bitmap images to record the hologram. For the first time to our knowledge, we managed to record a hologram of a bitmap image by continuously adjusting the laser beam polarization by SLM during scanning. The developed method can sabstantially improve hologram recording technology by increasing its speed, reducing the price, and eliminating complex processing procedures.
