Reflection Spectral Analysis of Fiber Bragg Gratings
We present a detailed experimental study of Bragg grating reflection spectra around the wavelength of λB = 1560 nm for different tilt angles set between the fiber and the phase mask. An optical Bragg grating is a transparent device with a periodic variation of the refractive index, so that a large reflectance (less precisely: reflectivity) may be reached in some wavelength range (bandwidth) around a certain wavelength which fulfills the Bragg condition where λ is the vacuum.

Spatial Light Modulator Holographic Imaging
Key themes include the use of SLMs in optical imaging, holography, adaptive optics, and telecommunications, highlighting their role in enhancing image quality and enabling advanced functionalities. Hubei Key Laboratory of Modern Manufacturing Quantity Engineering, School of Mechanical Engineering, Hubei University of Technology, Wuhan 430068, China School of Science, Hubei University of Technology, Wuhan 430068, China Author to whom correspondence should be addressed. Spatial light modulators (SLMs) are electro-optical devices, pertaining to manipulating the fundamental characteristics, viz. SLMs have gained significant attention of the research fraternity due to their versatile applicability in various optical. In addition to conventional two-dimensional imaging, these systems are useful for multidimensional imaging, axial sectioning. Abstract: The optimization of imaging accuracy and speed is a crucial issue in the development of computer-generated holograms (CGH) for three-dimensional (3D) displays. This paper proposes an optimized iterative algorithm based on the angular spectrum method (ASM) to achieve high-quality.
