About
My name is Arasad Ali Khan and I completed my PhD in Physics from the Department of Physics, National Institute of Technology Jamshedpur on 27th December 2024.
My research focuses on the design and implementation of holographic optical elements, specifically holographic lenses, and their various applications in interferometry and solar holography. For my PhD work, I utilized both the imaging and non-imaging properties of holographic lenses. I developed a compact coherent imaging system/interferometer that consists of four identical holographic lenses. I investigated the advantageous applications of this imaging system/interferometer in several areas, including measuring in-plane displacement components in speckle metrology, assessing various fracture parameters for an aluminium beam having central edge crack under a three-point bending test in fracture mechanics, and forming good-quality, uniformly spaced, undistorted fringes for Laser Doppler Anemometry (LDA) measurement. The results of these investigations have been published in reputable international journals.
On the other hand, the non-imaging properties of holographic lenses, specifically their wavelength and angular selectivity, were used to record an off-axis multiplexed lens for concentrator photovoltaics. Such multiplexed lens facilitates wavelength-selective operations with a wide acceptance angle in concentrator photovoltaics. This innovative approach offers a novel solution to the challenges associated with the limited tolerance angle (acceptance angle) of holographic lenses for concentrator photovoltaics, allowing for more efficient and effective use of solar energy.
