摘要 |
Reticle structure defining a succession of contiguous cells, separately discernible upon illumination thereof, is spacedly positioned relative to a discernible indicium, such as a light source. The indicium is disposed in a known location relative to the reticle structure and the cells and indicium are viewed jointly from a given location. Information is derived for use in determining the positional coordinates of the given location with respect to the indicium. |
