Abstract: An analog real-time signal processing device and method are presented. The device is configured to perform electrical signal processing. The device comprises an electronic circuit including at least one basic unit of electrodes, the basic unit being configured to be sensitive to an external field, such as input photon flux, indicative of a first input signal to cause emission of charged particles and configured to define at least one electrical input for a second input signal and one electrical output, thereby providing the electrical output in the form of an approximation of a product of the first and second input signals.

Abstract: A device and method are presented for use in measuring photon energy. The device comprises at least one pixel unit (10) including a Photocathode (12) that emits electrons in response to absorbed photons; an Anode (14); and a control unit (19) operable for controlling an electric current from the Photocathode (12) to the Anode (14) so as to selectively prevent electrons' arrival to the Anode (14) to thereby scan a spectrum of photon energies incident on the Photocathode (12).

Abstract: An electronic device is presented which is configured to operate as at least one logic gate. The device comprises an electrodes arrangement of one or more basic units, the basic unit being configured to define at least one vacuum space for free charged particles' propagation and comprising an input assembly for supplying an input signal, and a floating electrode assembly accommodated proximal said input assembly and serving for reading an output signal therefrom, the floating electrode arrangement being configured to define at least one source of the free charged particles and at least one target toward which the charged particles are directed and is chargeable and dischargeable in response to the input signal thereby creating the output of the basic unit.

Abstract: An electro-optical modulator device and method are provided. The device comprises a light modulator unit having a first Cathode for exposing to input light; and an electric field source configured to create an electric field affecting a change in the refractive index of the first Cathode, thereby effecting a change in the propagation of light reflected from or transmitted through the first Cathode, said light from the first Cathode enabling to affect the operation of an external light sensitive electronic device.
