  • Electric field sensor
    Patent number: 11782081
    Abstract: There is disclosed a device for determining a strength of an oscillating electric field. The device comprises an absorber to absorb radiation at the frequency of the oscillating electric field, and a thermal insulator transparent to radiation at the frequency of the oscillating electric field, which thermal insulator is arranged to thermally insulate the absorber. The device also comprises a first temperature sensor arranged to measure the temperature of the absorber, and a second temperature sensor arranged to measure the temperature external to the thermal insulator. Methods of measuring electric field using such a device, and methods of calibrating such a device, are also disclosed.
    Type: Grant

  • Workpiece positioning method and apparatus
    Patent number: 9063534
    Abstract: A method of relatively positioning a workpiece and a reference axis comprising effecting relative displacements of the workpiece and the reference axis along orthogonal axes so that an intersection of the reference axis with the workpiece is moved at substantially constant speed along a curvilinear path. The method is particularly applicable to SEE sensitivity mapping of a microchip memory using a pulsed laser, relative to the axis of which the chip is moved in a spiral path.
