We explore the adaptation of existing photolithography technologies and introduce the potential for additional functionality in the form of structured light. By using a complementary metal oxide semiconductor (CMOS) controlled micropixellated light emitting diode (LED) array, features such as object recognition, tracking and characterization are possible in combination with photo-curing. We discuss the observed trade off between the delivered power density and resolution capability of the system due to the requirements of the additional features.
