Expanded field of view frequency-selective incoherent holography by using a triple-beam setup

Area of Science:

• Optics and Photonics
• Holography
• Image Reconstruction

Background:

• Incoherent optical frequency selection is crucial for advanced imaging.
• Existing holography methods face limitations in resolution and field of view.
• Compressed holography requires efficient reconstruction techniques.

Purpose of the Study:

• To propose a novel method for incoherent optical frequency selection.
• To develop a reconstruction technique for compressed holography.
• To demonstrate three-dimensional reconstruction and phase extraction capabilities.

Main Methods:

• Developed three-pack frequency-selective incoherent holography.
• Utilized phase shift intercepts and spatial transfer function convolution for reconstruction.
• Implemented frequency-selective reconstruction to remove unwanted terms.

Main Results:

• Achieved compressed holography reconstruction without loss of magnification or resolution.
• Successfully performed three-dimensional reconstruction and selected-frequency phase extraction.
• Demonstrated submicron step axial slice reconstruction.

Conclusions:

• The proposed method offers a new approach to incoherent optical frequency selection.
• The technique shows potential for compressed holography, extended field of view imaging, and slice tomography.
