Abstract

We demonstrate single-shot multiwavelength digital holography using a monochromatic image sensor and spacebandwidth capacity-enhance experimentally. Multiple wavelength information is multiplexed on the monochromatic image sensor plane in the space domain and is separated in the spatial frequency domain by utilizing the the spatial frequency of interference fringes. Both transmission and reflective multiwavelength digital holography systems can be constructed with a simple optical setup. The recordable space bandwidth utilized for object waves is extended by the space-bandwidth capacity-enhance. Both the three-dimensional and multiple wavelength information of an object with rough surface and a transparent specimen was recorded and reconstructed without unwanted image components.
