Intensity Decay

Optical coherence tomography (OCT) delivers 3-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution method, OCT images experience some artifacts that lead to misapprehension of tissue structures. Speckle, intensity decay, and blurring are 3 major artifacts in OCT images. Speckle is due to the low coherent light source used in the configuration of OCT. Intensity decay is a deterioration of light with respect to depth, and blurring is the consequence of deficiencies of optical components. In this short review, we summarize some of the image enhancement algorithms for OCT images which address the abovementioned artifacts.

Zusammenfassung Kleinaperturige optische Komponenten mit komplexer Form spielen zunehmend eine Rolle bei Sensing- und Imagingapplikationen. Die messtechnische Charakterisierung dieser Bauteile stellt jedoch noch immer eine Herausforderung dar. Es wurde ein auf optischer Kohärenztomographie basierendes Verfahren entwickelt, welches in der Lage ist, die Form- und Zentrierung beider Funktionsflächen kleinaperturiger Linsen mit nur einer Messung zu erfassen. Die Herausforderung stellt dabei die Messung der dem Messkopf abgewandten Funktionsfläche dar, da diese aufgrund der Lichtbrechung an der dem Messkopf zugewandten Funktionsfläche verzerrt gemessen wird.
