Abstract

The invention relates to a method for fast phase modulation comprising at least one diffractive optical element (DOE) and a Digital Micromirror Device (1) for controlling the spatial phase of light emitted from a light source (4). The invention is characterized in that it comprises at least one first optical element (9) through which light coming from the light source (4) passes, at least one transparent diffractive optical element (10), and/or reflective diffractive optical element (11) located before or after the Digital Micromirror Device (1) and providing phase modulation of the light passing through the optical elements (9), at least one second optical element (9.1), which is used to reduce the post-modulation light to the target region (13), at least one data acquisition and/or controller element (12) for controlling the light reaching the target region (13).
