A Recording Structure for Extending the Detection Angle in Off-Axis Digital Holography
In digital holography, the sampling of the object wavefront is determined by the spatial resolution of the image sensors, which limits the angle range of the object wavefront. In this letter, we propose a recording structure for enlarging the detection angle in off-axis digital holography. Spatial a...

| description | In digital holography, the sampling of the object wavefront is determined by the spatial resolution of the image sensors, which limits the angle range of the object wavefront. In this letter, we propose a recording structure for enlarging the detection angle in off-axis digital holography. Spatial angular multiplexing is realized by adding a small aperture in the object beam, and the spherical wave is employed as the reference light. The experiment result indicate that the new recording structure can achieve a range of 14.5 degrees, which exceeds four times the angular capacity of conventional optical path detection methods. This proposed angle-multiplexed recording technique has the potential to enhance the demand and applicability of large field of view measurements in digital holography. |
