Area of Science:

• Optics
• Optical Engineering
• Image Reconstruction

Background:

• Traditional optical systems often face challenges with variable magnification.
• Achieving consistent image scaling across different object distances is crucial for many imaging applications.

Purpose of the Study:

• To propose and validate a 4-f optical configuration with fixed transverse magnification.
• To demonstrate that image scaling is independent of object and image sensor positions.

Main Methods:

• Utilizing a 4-f optical setup with a wavefront modulation device at the Fourier plane.
• Applying principles of Fourier optics and the optical matrix method for mathematical verification.
• Conducting numerical simulations and experimental validations.

Main Results:

• The proposed optical configuration yields reconstructed images with transverse magnification independent of object and sensor locations.
• Fixed transverse magnification allows for consistent scaling of objects at varying distances.
• Both simulation and experimental results confirm the stability of the reconstructed image scaling.

Conclusions:

• The developed 4-f optical system offers a robust solution for fixed-magnification imaging.
• This configuration simplifies image processing and analysis by eliminating the need for magnification correction.
• The findings have potential applications in microscopy, remote sensing, and other imaging fields.
