the diffractive multifocal iol provides simultaneous bifocal imaging by utilizing both diffractive and refractive optics. in both distant and near vision, there is a clear highly focused image on the retina. the second image is highly defocused, providing only faint background illumination. a small amount of the light goes to the higher orders of diffraction which are not perceptible by eyes. t...

Polycapillary x-ray optics provide an innovative new way to control x-ray beams. Placing these optics after the object to be imaged provides very efficient rejection of Compton scatter, while allowing image magnification without loss of resolution, image demagnification, or image shaping to match with digital detectors. Measured scatter rejection optics had primary transmissions greater than 50...

Optical techniques based on diffuse optics have been around for decades now and are making their way into the day-to-day medical applications. Even though physics foundations of these known many years, practical implementation technique were hindered by technological limitations, mainly from light sources and/or detection electronics. In past 20 developments supercontinuum laser (SCL) enabled t...

Polymers have many applications in various medical and industrial approaches. One of these polymers is polystyrene which has special properties to be considered as promising material different optics, biomedical, electronics fields. The addition metal oxides nanoparticles huge This article includes a recent review on oxide NPs doped polymer (such polystyrene). previous studies demonstrated the ...

Telemedicine is the use of telecommunications for medical diagnosis and patient care. Telecommunication technology allows for the provision of medical services to sites that are physically separated from the provider. The telemedicine communication link usually involves standard telephone service through high speed, wide bandwidth transmission of digital signals in conjunction with computer enh...
