Asymmetric integral imaging system for a see-through three-dimensional display with background imaging function

A see-through three-dimensional display with variable background imaging function is proposed. The proposed display system is based on integral imaging and consists of three lens arrays and a transparent flat-panel display. An asymmetric alignment of the three lens arrays enables variable background imaging. The background scene situated at any distance from the display system can be imaged at an intended distance from the display system. The possible imaging regions are shown. The proposed technique was experimentally verified using two optical systems that consisted of lens arrays with large and small lens pitches.
