Off-axis digital holography with multiplexed volume Bragg gratings

摘要

We report on an optical imaging design based on common-path off-axis digital holography, using a multiplexed volume Bragg grating. In the reported method, a reference optical wave is made by deflection and spatial filtering through a volume Bragg grating. This design has several advantages, including simplicity, stability, and robustness against misalignment. (C) 2018 Optical Society of America
