The Optical Measurement Group at Institute for Advanced Studies in Basic Sciences (IASBS) focuses on developing and applying advanced optical techniques for precise measurement and imaging. Our research covers a wide range of methods, including interferometry, spectroscopy, optical coherence tomography (OCT), and digital holographic microscopy (DHM), aiming to address challenges in both fundamental studies and practical applications. Established in 2012, the group has expertise in designing and implementing optical systems capable of measuring physical properties with high accuracy.

We collaborate with researchers and institutions to explore new possibilities in optical metrology, benefiting from shared expertise and specialized facilities. Our team is committed to innovation, accuracy, and interdisciplinary cooperation in all our projects. For inquiries and collaboration opportunities, please contact us via email at e.a.akhlaghi@iasbs.ac.ir.

$Optical metrology is a branch of measurement science that uses light to accurately assess the physical properties of objects—such as shape, dimensions, displacement, refractive index, surface roughness, temperature, and deformation. Thanks to the unique characteristics of light, including its non-contact and non-destructive nature, optical methods offer fast, remote, and precise measurements without disturbing the sample. These techniques rely on fundamental optical phenomena such as interference, diffraction, reflection, refraction, and absorption. They enable real-time imaging, high-resolution measurements, and the ability to investigate both surface and subsurface features of a sample.$

$Common techniques include interferometry and diffractometry for detecting nanoscale displacements or surface variations, spectroscopy for analyzing material composition and optical behavior. Advanced optical imaging systems, such as confocal microscopy, fluorescence microscopy, digital holographic microscopy (DHM), and optical coherence tomography (OCT), are also widely used for high-resolution and 3D imaging. Due to its precision and versatility, optical metrology plays a critical role in a wide range of applications across physics, engineering, medicine, microelectronics, photonics, biotechnology, and materials science.$
