Exploring the Versatility of Fabry-Pérot Interferometers: From Spectroscopy to Sensing
Abstract: The fundamental concept of operation for the Fabry-Perot interferometer is interference. Coherent light bounces back and forth between two extremely reflecting mirrors as it travels through the interferometer. The device operates on a pattern of constructive and destructive interference that is produced by this. By carefully regulating the space between the mirrors, a resonant optical cavity is created. The Fabry-Perot interferometer (FPI) is one of the most important and versatile …

Identification of Diabetic Foot Ulcer by Using Filter and Pixel Classification Methods
Abstract: Ulceration of the foot in diabetes is common and disabling and frequently leads to amputation of the leg. Mortality is high and healed ulcers often recur. The pathogenesis of foot ulceration is complex, clinical presentation variable, and management requires early expert assessment. Interventions should be directed at infection, peripheral ischaemia, and abnormal pressure-loading caused by peripheral neuropathy and limited joint mobility. Despite treatment, ulcers readily become chronic wounds. Diabetic foot …
