    摘要： A vacuum tube photodetector includes a planar photocathode, a parallel high voltage accelerating mesh, and a planar output anode positioned adjacent to and spaced from the mesh. The anode and mesh are connected to the inner and outer concentric conductors of a high frequency coaxial transmission line coupled to a load or output device. The high voltage preacceleration of electrons by the mesh and the small mesh to anode spacing provide a significant reduction of electron transit or pulse rise time compared with known two element biplanar photodiodes. In addition, the vacuum seal between the anode and mesh is positioned adjacent the anode-mesh gap which greatly reduces pulse decay time and undesired reflections. The mesh and anode are at the same potential to eliminate the usual high bias voltage between inner and outer coaxial photocathode and anode electrodes of the biplanar tube, as well as a coaxial coupling capacitor.

    摘要： A light detector based on the fact that the field emission from a photoconductive material varies depending on a variation in the intensity of the light to which said photoconductive material is exposed, said detector comprising basically a field emission cathode of a photoconductive semiconductor in the form of a pointed whisker, and an electron collector for collecting the electrons emitted from said cathode, an appropriate accelerating voltage being applied between said cathode and said collector.
