Abstract
A probe includes an elastic element having first and second ends, a transmitter, one or more receiving antennas and one or more narrow-band amplifiers. The transmitter is coupled to the first end and is configured to transmit signals in a given range of frequencies. The one or more receiving antennas are coupled to the second end and are configured to receive the signals. The one or more narrow-band amplifiers have a pass-band that matches the given range of frequencies and are configured to amplify the signals received by the one or more receiving antennas, respectively.
Claims20
A probe, comprising:
- an elastic element having first and second ends;
- a transmitter, coupled to the first end and configured to transmit signals in a given range of frequencies;
- one or more receiving antennas coupled to the second end and configured to receive the signals;
- and
- one or more narrow-band amplifiers, which have a pass-band that matches the given range of frequencies and which are configured to amplify the signals received by the one or more receiving antennas, respectively.
A method for producing a probe, the method comprising:
- providing an elastic element having first and second ends;
- coupling, to the first end, a transmitter for transmitting signals in a given range of frequencies;
- coupling, to the second end, one or more receiving antennas for receiving the signals;
- and
- coupling, to the receiving antennas one or more respective narrow-band amplifiers, which have a pass-band that matches the given range of frequencies for amplifying the signals received by the one or more receiving antennas, respectively.
A method, comprising:
- transmitting signals in a given range of frequencies, using a transmitter coupled to a first end of an elastic element, which is disposed in a probe and has first and second ends;
- receiving the signals, using one or more receiving antennas coupled to the second end;
- and
- amplifying the signals received by the one or more receiving antennas, using one or more respective narrow-band amplifiers, which have a pass-band that matches the given range of frequencies.
