摘要: An illumination system for use in a system (1) for layerwise production of a tangible object (5) in a liquid reservoir (2) comprises an image forming element (21), an image projection system (22, 23) and a microlens array (7). The illumination system (20) further comprises a controller (24) for controlling the microlens array (7) to perform a movement (9) which is relative to at least part of the image projection system (22, 23) and for controlling the image forming element (21) to form time-varying two-dimensional images synchronously with said movement in such way that microspots (17) describe and solidify a predetermined area of a liquid layer (10) when said movement (9) is also relative to the object (5) under construction.
