Optics for Micron-Scale Resolution & Low-Noise OCT
Optical Coherence Tomography (OCT) has emerged as a powerful, non-invasive imaging technique that delivers real-time cross-sectional views of biological tissues with micrometer-scale resolution. The ability of OCT to reveal structural details beneath the surface of tissues—without physical contact—relies heavily on the quality and precision of its optical components.
From broadband light sources to interference optics and scanning mechanisms, each component in an OCT system must meet strict tolerances for wavefront quality, alignment, and dispersion control. This article explores the role of high-precision optics in OCT systems, covering technical principles, key optical elements, manufacturing challenges, and practical solutions.
