Subsurface damage (SSD) induced during the processing of optical components, which are key parts large systems, can deteriorate system performance or complete system. To eliminate SSD components in subsequent processing, it must be accurately detected. This paper presents a review principle, characteristics, research status, and development trends detection methods for components. finds that de...

IMPORTANCE Hydroxychloroquine sulfate retinopathy can progress after the drug is stopped. It is not clear how this relates to the stage of retinopathy or whether early screening with modern imaging technology can prevent progression and visual loss. OBJECTIVE To determine the relationship between progression of retinopathy and the severity of disease using objective data from optical coherenc...

Red light has been shown to increase sperm swimming speeds, but there is little characterization of its effect on DNA or swimming force. In this study 633nm laser light irradiation did not induce significant levels of oxidative DNA damage.

Over the past few decades, there has been a considerable interest in the use of distributed optical fibre sensors (DOFS) for structural health monitoring of composite structures. In aerospace-related work, health monitoring of the adhesive joints of composites has become more significant, as they can suffer from cracking and delamination, which can have a significant impact on the integrity of ...
