Description

one

Iabrebeshe belongs to the pulse technique and is intended to generate electrical and light signals.

An optoelectronic generator, a socceded capacitor, its charge circuit from a constant voltage source and a discharge circuit to a load through a photo switch are known.

However, this generator generates only relatively short pulses of exponential form.

Most closely related to the technical essence of this invention is an optoelectronic generator comprising a light source, resistors, a photodiode, a constant voltage source, a transistor and a capacitor 2.

This generator generates electrical impulses of practically rectangular shape in a wide range of durations, but does not produce the light signals necessary in a number of cases, which limits its functionality.

The purpose of the invention is to enhance the functionality of an optoelectronic generator.

To achieve this goal, an optoelectronic generator containing a source of luminous flux, first and second resistors, a photodiode and a constant voltage source, the photodiode connected through a first resistor in the opposite direction to a constant-voltage source, is fixed / loose movable reflector, the control electrodes of the piezoelectric elements connected in parallel to the photodiode and the second resistor, and the photodiode and the output of the light signal of the generator are optically connected to the source cBeTOBtro flow through the mobile th reflector.

In addition, in the generator entered n

20 additional sources of light fluxes with which 2n light signal outputs are optically coupled through a movable reflector.

The drawing shows an electrical circuit diagram of the device.

The Otiroelectronic generator contains a source of light flux I, an output of a light signal 2, a fig.6 diode 3, resistor 4 and 5, a source of constant voltage, connected to terminals 6 and 7 and a piezo element 8 with a fixed movable reflector 9, which is made in the form of a plate. The piezoelectric element 8 consists of

two crystals 10 and 11 with electrodes 12, 13 and 14. Electrodes 12 and 14 are placed on the side faces of the crystal / crystal 1 O and 11, are combined and form the first control electro. The electrode 13 is placed between the crystals 10 and 11 and forms the second control electrode. Photodiode 3 through the first resistor 4 is connected in the opposite direction to a constant voltage source. The control electrodes of the piezoelectric element 8 are connected in parallel with the photodiode 3 and the second resistor 5, the Photodiode 3 and the output of the light signal 2 are optically coupled to the light source 1 through the reflector 9. The electrical signal is removed from terminal 15. In addition, the generator contains additional light sources 16 ....... 16 ,, optically coupled through the reflector 9 to the outputs of the light signals 17 ...... 17 and 18 .... 18,

Optoelectronic generator operates as follows.

When voltage is applied to terminals 6 and 7, an electric field arises between the electrodes of the piezoelectric element 8, under the action of which the piezo crystals Yu and 11 are mechanically deformed, as a result of which the reflector 9 is deflected. The combination of crystals 10 and 11 with opposite poles doubles the effect. In this case, the luminous flux emitted by the source of ohm 1, reflected from the deflected reflector 9, falls on the photodiode 3, the resistance of which under the influence of light decreases. The supply voltage for the most part falls on a resistor 4, and a rectangular electric pulse is formed on the generator terminal 6 and 15. A low potential is established on the control electrodes of the piez e kmenta 8, the deformation of piezo crystals 1O and 11 disappears, and the reflector 9 returns

In the initial position at which the reflected beam hits the optical output 2, the resistance of the photodiode 3 increases and on the control electrodes of the piezoelectric element 8, as well as at terminal 15, a high voltage level reappears. Svetovy / e streams from additional light sources 16 16 reflected

from the reflector 9, which is in its original position, is directed to the optical outputs 17 17 |, or codes 18

 I8j when reflector 9 is rejected.

Thus, an optoelectronic generator allows receiving, in addition to rectangular electric pulses, also light, and the introduction of additional light sources into the generator II makes it possible to obtain additional light output signals of different power and spectral composition.
