Fourier transform holography using a quasimonochromatic incoherent source

Area of Science:

• Optics and Photonics
• Holographic Imaging

Background:

• Incoherent holography often suffers from a bias problem, limiting its practical applications.
• Recording Fourier transform holograms with partially coherent light presents unique challenges.

Purpose of the Study:

• To investigate the feasibility of recording Fourier transform holograms using a quasimonochromatic incoherent source.
• To address the bias problem in incoherent holography while analyzing the trade-offs involved.

Main Methods:

• Utilizing a quasimonochromatic incoherent source for illumination.
• Recording elementary holograms that collectively reconstruct the entire object.
• Employing Fourier transform principles for hologram formation.

Main Results:

• Successfully recorded Fourier transform holograms with partially coherent light.
• The proposed method partially resolves the bias issue inherent in incoherent holography.
• A trade-off between bias reduction and image resolution was observed.

Conclusions:

• Fourier transform holography is achievable with quasimonochromatic incoherent sources.
• The technique offers a partial solution to the bias problem in incoherent holography.
• Careful consideration of resolution trade-offs is necessary for practical implementation.
