OCT began in ophthalmology and remains one of its most impactful technologies. The convergence of spectral-domain detection, holographic grating advances, high-speed camera development, and the clinical demands transformed OCT into the standard of care for retinal disease management.
At the core of every high-performance ophthalmic OCT system lies a carefully engineered spectrometer. Its speed, sensitivity, optical efficiency, and regulatory robustness directly determine clinical image quality and diagnostic reliability.
For developers of OCT systems, spectrometer performance is not merely a component specification — it is foundational to clinical success.
Optical Coherence Tomography Angiography (OCT-A) is a powerful extension of OCT that enables visualization of blood vessels without the need for exogenous contrast agents. Unlike fluorescein angiography or indocyanine green angiography, OCT-A provides depth-resolved vascular imaging, allowing clinicians and researchers to localize vessels within specific tissue layers.
Today, OCT-A remains the only widely adopted technique capable of imaging microvasculature in three dimensions, non-invasively, and without injected dye. Most common applications are investigating stent failure and plaque build up.
System Integrators have developed proprietary dual weld and inspection heads whereby, the SLED illumination source is projected co-axially through the same optics as the welding laser. This provides real time SD-OCT weld penetration depth measurements with micron level precision at imaging depths down to 14mm at speeds of up to 250kHz. Primary application is EV battery weld monitoring.
Spectra Domain OCT represents a transformative advancement in the inspection and control of material processing applications. By providing real-time, high-resolution access to subsurface structures, OCT addresses a critical unmet need that has long limited the reliability of these technologies. More than just an inspection tool, OCT serves as a bridge between observation and control, enabling a new generation of intelligent manufacturing systems.
As integration challenges are overcome and data analytics capabilities mature, OCT is poised to become a cornerstone of advanced, high-precision production environments.
