Laser differential confocal lens refractive index measurement.
A new laser differential confocal lens refractive index measurement is proposed, which uses the absolute zero of the differential confocal axial intensity curve to precisely identify the positions of the objective when the measurement pencil is focused on the vertex of the test lens and the reflector with or without the test lens in the measurement light-path, and then uses aberration compensat...
متن کاملRefractive index measurement of the isolated crystalline lens using optical coherence tomography
An optical coherence tomography system has been developed that was designed specifically for imaging the isolated crystalline lens. Cross-sectional OCT images were recorded on 40 lenses from 32 human donors with an age range of 6-82 years. A method has been developed to measure the axial thickness and average refractive index of the lens from a single recorded image. The measured average group ...
متن کاملUltrasonic Refractive Index Tomography
Ultrasonic computed tomography (UCT) is one of the methods capable of tissue characterization. It is expected to provide not only a quantitative image but also diagnostic information. As in X-ray CT, UCT requires a projection data to reconstruct a cross-sectional image. In UCT such projection data are derived from the received broadband ultrasonic signal. In this paper, two methods for deriving...
متن کاملDetermining the Refractive Index of Articular Cartilage Using Confocal Microscopy
Articular cartilage (AC) is a type of hyaline covering material for the articulating ends of bones of synovial joints which transmits high loads and maintains contact stresses at an acceptably low level. There have been numerous studies focusing on the assessment of the AC degeneration. The measures which have been utilized to evaluate the level of AC degeneration include morphology, wear parti...
متن کاملBroad Wavelength Range Metal-Enhanced Fluorescence Using Nickel Nanodeposits
We describe the use of surface-deposited nickel nanoparticles to enhance the fluorescence signatures of fluorophores. Different density Ni nanoparticulate substrates were fabricated and characterized using both AFM and optical absorption techniques. When fluorophores were placed in close proximity to the substrates, metal-enhanced fluorescence (MEF) was observed. The wavelength dependence of th...
