This kit is an aerial bomb glide range extension kit, similar to the American Joint Direct Attack Munition Extended Range (JDAM-ER). The guidance system and gliding function of the UMPK kit can provide ordinary aerial bombs with longer-range and more accurate strike capabilities.
The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens , which refracts light rays so that a point source of light is seen as a ...
Esotropia (from Greek eso 'inward' and trope 'a turning' [1]) is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [2]
Porro prisms are most often used in pairs, forming a double Porro prism. A second prism rotated 90° with respect to the first, is placed such that light will traverse both prisms. The net effect of the prism system is a beam parallel to but displaced from its original direction, with the image rotated 180°.
The Bureau of Corrections (Filipino: Kawanihan ng Pagwawasto, [3] literally "Bureau of Corrections", of which it was known as the Bureau of Prisons from 1905 to 1989; abbreviated BuCor) is an agency of the Department of Justice which is charged with the custody and rehabilitation of national offenders, commonly known as Persons Deprived of ...
A Perger prism or Perger–Porro prism system is a prism, that is used to invert (rotate by 180°) an image. The special feature of this prism is that, like a traditional double Porro prism system, it manages this with only four beam deflections and has neither a roof edge with the accompanying phase correction problems, a mirrored surface or ...
The motor system acts to point both eyes at the target of interest; any offset is detected visually (and the motor system corrects it). Heterophoria occurs only during dissociation of the left eye and right eye, when fusion of the eyes is absent.
