focal point and focal k-plane

چکیده
this paper deals with the basic notions of k-tautimmersions . these notions come from two special cases; that is, tight and taut immersions. tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. we generalize hight and distance functions to cylindrical function and define basic notions of k-taut immersions such as k-plane normal bundle , end k-plane map, focal k-plane, and critical k-plane normal. then we prove index theorems for cylindrical function similar to the standard index theorems of distance function . in this way, the key point is the relation between focal point and focal k-plane

متن کاملSNAP Focal Plane
The proposed SuperNova/Acceleration Probe (SNAP) mission will have a two-meter class telescope delivering diffraction-limited images to an instrumented 0.7 square-degree field sensitive in the visible and near-infrared wavelength regime. We describe the requirements for the instrument suite and the evolution of the focal plane design to the present concept in which all the instrumentation – vis...
متن کاملFocal Plane Instrumentation of VERITAS
VERITAS is a new atmospheric Cherenkov imaging telescope array to detect very high energy gamma rays above 100 GeV. The array is located in southern Arizona, USA, at an altitude of 1268m above sea level. The array consists of four 12-m telescopes of Davies-Cotton design and structurally resembling the Whipple 10-m telescope. The four focal plane instruments are equipped with high-resolution (49...
متن کاملMosaicked Multispectral Focal Plane Arrays
A mosaicked sensor is a monolithic array of many sensors, arranged in a geometric pattern. In the commercial digital color camera market, the mosaicked color filter array (CFA) technique is widely used, in which instead of using three charged coupled devices (CCDs) to capture the red, green, and blue spectral bands for each pixel, each pixel is associated with just one device covered by an opti...
متن کاملfocal point review
Raman spectroscopy is a powerful biochemical analysis technique that allows for the dynamic characterization and imaging of living biological cells in the absence of fluorescent stains. In this review, we summarize some of the most recent developments in the noninvasive biochemical characterization of single cells by spontaneous Raman scattering. Different instrumentation strategies utilizing c...
متن کاملFocal Point Key Facts
Idiopathic laryngeal hemiplegia (ILH) is the most common cause of upper respiratory unsoundness in horses. Classified as a distal axonopathy, ILH primarily affects the intrinsic laryngeal muscles on the left side. The adductor muscles are more severely affected at an earlier stage than is the primary abductor muscle. Endoscopic evaluation in standing or exercising horses can result in a definit...
