Scanning diffracted-light photography using white-light and thermal radiation sources
Abstract:
A 4-f imaging arrangement of lenses with a camera and a rotating slit placed at the Fourier plane of the system was used to obtain the optical disturbance produced by a macroscopic sample. The sample was illuminated by collimated beams from white-light and thermal radiation sources. The agreement between simulated and experimental results, obtained by processing the captured images using a Fourier ptychographic algorithm, demonstrates that scanning with the slit the direction of the light diffracted by the sample permits achieving the image diversity necessary for successful implementation of the scanning diffracted-light imaging technique.

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...
