This observation led to theconceptionof camera lenses of variable focal length in which the variation is obtained by moving one or more elements. One simple design consists of two fixed convex (converging) lenses of unequalpowerwith a movable concave (diverging) lens between them. When the centra...
The size of the image and whether it is erect or inverted, real or virtual, depend on the distance of the object from the lens or mirror relative to the focal length and on the type of lens or mirror (plane, convex, or concave) employed. The Columbia Electronic Encyclopedia™ Copyright...
The sensor unit of FIG. 2 has an optical system 64, which is, again, common to the passive sensor and to the LADAR-sensor. In the embodiment of FIG. 2, the optical system 64 comprises an annular concave mirror 66, which faces the observed field of view, and a convex secondary mirror...
