Exploratory study assesses SLEDs in low-coherence imaging, highlighting their benefits for medical applications.
This paper explores the fundamental physics and structural design of superluminescent light-emitting diodes (SLEDs), which serve as low temporal coherent light sources in optical coherence tomography (OCT). It begins with a concise overview of the concepts of temporal and spatial coherence, followed by an examination of different types of SLEDs, focusing on their architecture, performance characteristics, and specific advantages in medical imaging. Finally, we discuss applications of SLEDs in low-coherence interferometry techniques such as OCT that can be developed by new types of SLEDs.
