"enhance vector field state uniformity and optical resolution... 3 types: sensor-based, quasi-sensorless, and modal-sensorless... vectorial field feedback control... laser systems, biomedical imaging (microscopes), planetary observation such as galaxy detection (telescopes), and laser-based and lithographic nanofabrication such as of integrated circuit chips"
