Laser interferometry is a precision measurement technique that uses the interference of laser beams to detect minute changes in distance, displacement, or refractive index. It is widely used in applications such as gravitational wave detection, metrology, and optical coherence tomography due to its high sensitivity and accuracy.

Gravitational wave detection involves observing ripples in spacetime caused by massive accelerating objects, such as merging black holes or neutron stars, and provides a new way to study the universe beyond electromagnetic radiation. This groundbreaking field relies on highly sensitive instruments like LIGO and Virgo to measure incredibly minute distortions in spacetime, opening up new avenues for understanding fundamental physics and cosmology.

Metrology is the science of measurement that ensures the accuracy, precision, and reliability of measurements across various fields, from scientific research to industrial applications. It encompasses the development of measurement standards, calibration techniques, and error analysis to maintain consistency and comparability of measurements worldwide.

Metrology

Optical Coherence Tomography (OCT) is a non-invasive imaging technique that uses light waves to capture micrometer-resolution, three-dimensional images from within optical scattering media, such as biological tissues. It is widely used in medical fields like ophthalmology to assess the retina and diagnose conditions like macular degeneration and glaucoma.
