Abstract
An optically-based analogue-to-digital converter includes a first combiner with a first input for an optical reference signal, and a second input for an input signal that is to be digitised, a second combiner with a first input for a pulsed laser signal, and a second input, which is connected to the output of the first combiner, and an evaluation unit, which evaluates the output signal of the second combiner.
Claims19
An optically-based analogue-to-digital converter comprising:
- a first combiner with a first input for an optical reference signal, and a second input for an input signal that is to be digitised;
- a second combiner with a first input for a pulsed laser signal, and a second input connected to an output of the first combiner;
- and
- a quantum pulse gate connected to an output of the second combiner and including an output that outputs at least one optical signal to at least one optoelectronic converter for conversion into at least one analog signal which is in turn converted into at least one digital signal.
