ictus,raptus,seizure- a sudden occurrence (or recurrence) of a disease; "he suffered an epileptic seizure" cortical epilepsy,focal epilepsy- epilepsy in which the attacks begins with an isolated disturbance of cerebral function (as a twitching of a limb or an illusory sensation or a mental dist...
The concentrator thickness significantly affects the performance of the parabolic trough collector. To examine the effect of mirror refraction in the concentrator, the focal plane concentration for different concentrator thicknesses was studied using theoretical calculations, simulations, and experimental ...
focal plane如何读 英:[ˈfəʊkəl plein] 美:[ˈfokəl plen] focal plane是什么意思 焦平面 focal plane英英释义 noun a plane that is perpendicular to the axis of a lens or mirror and passes through the focus noun a plane that is perpendicular to the axis of a lens or mirror...
We study a novel focal plane wavefront sensing and active optics control scheme at the VST on Cerro Paranal, an f/5.5 survey telescope with a 1x1 degree field of view and a 2.6m primary mirror. This scheme analyzes the elongation pattern of stellar PSFs across the full science image (256...
A convex mirror of focal length f=-30cm faces a plane mirror, which is 10cm away from it, with the convex mirror on the left. An object sits at a distance of 5cm away from the convex mirror (directly between the two mirrors). Consider ...
(Supplementary Fig.4and Methods). Although this clustering reduces the number of physically accessible pixels of the FPA to 63, the distributed nature of the 283,500 plasmonic nanoantennas positioned uniformly across the entire image plane—when combined with their high SNR and large bandwidth—...
A High-Speed Focal-Plane Shutter Framing Camera A rotating mirror framing camera which operates in the million frame per second range is described. The camera is based on the principle of the focal-plane shutter, making use of six shutter slits to record 216 frames in six rows of imag......
The front focal length is then the distance between the front focal point (in the front focal plane) and the front principal plane (see Figure 2). Some authors define the focal length to be negative in the situation of Figure 2 because the focal point is located before the front principal...
