专利汇可以提供Reference insertion device专利检索，专利查询，专利分析的服务。并且A novel device in the general nature of an autofocus enlarger that is coupled to a projector/collimator, which is distinctive by virtue of its greatly expanded range of magnification, and its ability to dynamically produce a view of a target which continuously enlarges, thus to realistically depict a constant rate approach. The capabilities of our device are attained utilizing a macro lens having a range of magnification of from approximately 1/24th to 5 times the image source size, providing a variation in magnification of approximately 125 to 1 without physical inversion of the lens being necessary. This lens is arranged to be moved in a preestablished relationship to other components of our device such that a target scene or the like may be maintained in focus on a continuous basis throughout all changes in magnification, even though these be very rapid changes. In order that our machine could depict extreme ranges of magnification, we evolved a novel compound cam arrangement such that the table or plate upon which the macro lens is mounted is, quite desirably, caused to move very rapidly in accordance with classical lens formula requirements at a time near what may be regarded as the end of the run. Thus, the extremes of velocity required for a very realistic simulation of a range closure are made possible, amounting to a dynamic presentation that may, for example, be quite effectively utilized as a so-called missile exerciser, arranged to simulate an actual flight of a missile for the benefit of the tracker of such missile, or as a reference insertion device serving to dynamically project an aerial photograph or the like directly into the tracker.，下面是Reference insertion device专利的具体信息内容。
