摘要： Arrangement to measure precisely probe-to-model board distance in a simulator. A source of radiation (17) is positioned to emit a beam (19) toward a model board surface (20) on which a scaled terrain model is constructed. A fixed position lens (15) collects reflected radiation and directs it onto a sensor device (16) which develops an electrical signal indicative of displacement of the reflected beam, which, in turn, varies directly as the distance between the probe (10) and the model board surface. One embodiment describes an arrangement in accordance with the Scheimflug condition whereby focus is maintained without concern for the depth of field as the probe approaches and withdraws from the surface of the model board.

摘要： A simulated view on a viewing surface of a raster scan television display of a changeable illuminated area located on a plane surface is provided. The source of illumination is a cone of light whose apex can be located at any distance from an eyepoint and the plane surface and whose conical surface intersects the plane surface creating the illuminated area. One element (78) of the invention as shown in Fig. 8 develops orientation signals representative of the relative geometrical orientations of the plane surface, eyepoint and cone of light. Line of sight signals representative of the position on the viewing surface of a line of sight from the eyepoint, through the viewing surface to a plane surface intersection point are also developed, by another element (80). The line of sight signals and orientation signals are combined in a signal processor (82) to generate a signal representative of the location of the intersection point relative to the conic section which results from the intersection of the cone of light with the plane surface. A signal comparator (84) determines whether the intersection point is within or without the conic section, and controls a video processor (86) to create an illumination area on the viewing surface corresponding to the plane surface intersection point when the point lies within or on the conic section.
