The Imaging X-ray Polarimetry Explorer, a NASA small explorer mission, will be the first mission dedicated to x-ray polarimetry. payload consists of three identical telescopes, each comprising mirror module assembly (MMA) with polarization-sensitive detector at its focus. We describe all aspects MMA, from initial optical and mechanical design considerations meet program requirements through she...

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...

The human eye treated as an optical system is an excellent model to teach various aspects of Optics. The range of topics treated can start from simple refraction upto quantum optics including detection of single photons. In particular, concepts and methods such as ray tracing, apertures and stops, field of view calculations, gradient index systems, non-centered systems, Fraunhofer and Fresnel d...

Transformation optics has been used to propose various novel optical devices. With the help of metamaterials, several intriguing designs, such as invisibility cloaks, have been implemented. However, as the basic units should be much smaller than the working wavelengths to achieve the effective material parameters, and the sizes of devices should be much larger than the wavelengths of illuminati...

A light ray in space is characterized by two vectors: (i) a transverse spatial vector associated with the point where intersects given spherical cap; (ii) an angular-frequency which defines direction of propagation. Given propagating from emitter to receiver, linear equation established that links its representative vectors on and receiver. The link expressed means matrix not homogeneous, since...
