We explain how to concentrate light simultaneously at multiple selected volumetric positions by means of a 4D illumination light field. First, to select target objects, a 4D imaging light field is captured. A light field mask is then computed automatically for this selection to avoid illumination of the remaining areas. With one-photon illumination, simultaneous generation of complex volumetric light patterns becomes possible. As a full light-field can be captured and projected simultaneously at the desired exposure and excitation times, short readout and lighting durations are supported.
我们通过 4D 照明光场解释了如何同时将光集中在多个选定的体积位置上。首先，为了选择目标物体，捕获了 4D 成像光场。然后，为了避免照明其余区域，自动计算光场掩模进行选择。通过单光子照明，可以同时生成复杂的体积光图案。由于可以同时捕获和投影完整的光场，并在所需的曝光和激发时间进行照明，因此支持短读取和照明持续时间。
