As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted the attention of both academia and industry due to its distinctive optical properties and wide applications. Recently, MLA has gradually stepped into diverse application fields, such as wave front sensing, virtual reality/augmented reality display, beam shaping, micro/wide viewing angle imaging, light-field camera, optical communication and many other emerging applications.
