Patent ID: 7656917

Claim:
A circuit arrangement for generating light pulses, comprising: an electro-optical converter; a switching element; a charge store, wherein the electro-optical converter is connected to the charge store via the switching element, and wherein a closing of the switching element triggers a discharging process in the charge store which generates an electrical pulse that is converted to a light pulse in the electro-optical converter; a first impedance matching circuit, comprising at least one resistor and at least one capacitor, operationally connected between the charge store and the switching element to match impedance between the charge store and switching element and to compensate for the parasitic inductances of the charge store and the switching element such that current and/or voltage waves, reflected between the switching element and the charge store, are minimized; and a second impedance matching circuit, comprising at least one resistor and at least one capacitor, operationally connected between the switching element and the electro-optical converter to match impedance between the switching element and electro-optical converter and to compensate for the parasitic inductances of the switching element and the electro-optical converter such that current and/or voltage waves, reflected between the electro-optical converter and the switching element, are minimized.
