Digital Holography and Microscopy

Digital inline holography paves the way to reconstruct three-dimensional object fields by recording the interference between an object wave and a reference wave. Captured interference pattern contains the information about the object and it is obtained by performing numerical calculations. Inline setups suffer from st…

Oxidative stress is an important cellular phenomenon that’s necessary for the cell to maintain its metabolic activities but causes adverse complications due to abnormal accumulation. It may cause some changes in the mechanical structure and behavior of the cells by affecting the cell membrane and cytoskeleton structur…

This study presents an optical profilometry approach implemented using a four-core, multimode optical fiber in combination with the two-dimensional Continuous Wavelet Transform (2D-CWT). A He–Ne laser beam with a wavelength of 632.8 nm and a spot size of 0.7 mm was precisely aligned and coupled into the central region…

Abstract In this study, we present a double-Gate interferometer based on three beam splitters that generates, in a single exposure, a superimposed orthogonal fringe pattern formed by two orthogonal sinusoidal fringe families. By controlled rotation of the second and third beam splitters, the spatial carriers of the ve…

Reflectance confocal microscopy (RCM) provides noninvasive, cellular-resolution "optical biopsies" of human skin \emph{in vivo} by acquiring en-face images at successive depths, forming a sparse z-stack. Due to optical limitations, these stacks are anisotropic 3D volumes with lateral resolution (0.5 $μ$m) $\sim$6 time…

Lensless cameras based on thin diffusers offer a compact alternative to conventional refractive imaging but rely on computational reconstruction, since the diffuser's point spread function (PSF) globally multiplexes every scene point across the sensor. Here, we report a Fourier Neural Operator (FNO) framework for this…
