    摘要： An optical lens system is provided having the capability of selectively varying the peripheral field curvature to improve focusing for nonplanar objects and for special photographic effects. The lens system can include in sequence, a first lens group of positive refractive power, a second lens group of negative refractive power and a third lens group of positive refractive power. The specific refractive power of the first and second lens group are designed so that the optical ray traces from an object on the optical axis at infinity will run approximately parallel with the optical axis in the space between the second and third lens groups. The first and second lens groups being movable as a unit relative to the third lens group to change the field curvature without varying the back focal distance of the lens system.

    摘要： A method for ready and thorough erasure of information in a scan converter storage tube of the class including an electron gun of an electrostatic focus and deflection variety and a storage target having a substrate made from sapphire or like monocrystalline insulator. The storage surface of the substrate is first primed by a scanning electron beam from the electron gun while the potential of a collector electrode on the storage surface is set higher than the value which is lower than the potential of the field mesh electrode of the electron gun by up to about 100 volts. Then the storage surface is again scanned after setting the collector electrode potential higher than the potential of the cathode included in the electron gun and at such a value that the storage surface potential with respect to the cathode potential becomes less than a potential at which the secondary emission ratio of the monocrystalline substrate first becomes unity. Thus, as the storage surface acquires the cathode potential as a result of the scanning, a prewrite potential difference is established between storage surface and collector electrode.

    摘要： The present lens system is capable of providing both a zooming operation and also a relatively efficient and economical macrophotography mode of operation. The zoom lens system contains the basic conventional lens groups of a focusing lens group, variator lens group, compensator lens group and relay lens group. These individual lens group function in a conventional manner during a zooming mode of operation. However, during the macrophotography mode of operation, the individual lens element that form the relay lens group are capable of coordinate movement with other lens elements in the lens system to provide a relatively compact and economical lens design for macrophotography. Thus, the relay lens group is not only capable of performing its normal auxiliary function of image transmission and final balancing of aberrations imposed by the design parameters of the zoom mode of operation but is further capable of compensating for the introduction of aberrations that will occur in the macrophotography mode of operation. In some embodiments, the plurality of movable lens elements that form the relay lens group has at least that movable lens element closest to the design image plane moved to provide the second macrophotography mode of operation.
