A system and associated method for analyzing a smoking article filter is provided. An emitter emits an initial signal toward a smoking article filter. The initial signal may have a frequency between about 0.1 teraHertz and about 10 teraHertz. A sensor may detect a resultant signal resulting from interaction of the initial signal with the smoking article filter. An analysis unit may receive the resultant signal from the sensor, determine a filter status based on the resultant signal, and output an indicium indicative of the filter status. The filter status may include a capsule presence within the smoking article filter, a capsule absence from the smoking article filter, a proper insertion of a capsule into the smoking article filter, a defective insertion of a capsule into the smoking article filter, a proper capsule within the smoking article filter, and a defective capsule within the smoking article filter.

1. A system, comprising: an emitter and a sensor configured to receive a smoking article filter therebetween, the emitter being configured to emit an initial signal, the initial signal having a frequency between about 0.1 teraHertz and about 10 teraHertz, toward the smoking article filter;the sensor
1. A system, comprising: an emitter and a sensor configured to receive a smoking article filter therebetween, the emitter being configured to emit an initial signal, the initial signal having a frequency between about 0.1 teraHertz and about 10 teraHertz, toward the smoking article filter;the sensor being configured to detect a resultant signal resulting from interaction of the initial signal with the smoking article filter while traveling therethrough;a movement apparatus configured to linearly displace the smoking article filter along a longitudinal axis thereof and simultaneously rotate the smoking article filter about the longitudinal axis relative to the sensor and the emitter while the emitter emits the initial signal; andan analysis unit configured to receive the resultant signal from the sensor, determine a filter status based on the resultant signal, and output an indicium indicative of the filter status. 2. The system of claim 1, further comprising a converging lens configured to focus the initial signal perpendicularly to the longitudinal axis of the smoking article filter and a collimator lens configured to substantially straighten the resultant signal. 3. The system of claim 1, wherein at least one of the converging lens and the collimator lens comprises polymethylpentene. 4. The system of claim 1, wherein the analysis unit is configured to determine at least one of a transmission time of the resultant signal and an amplitude of the resultant signal. 5. The system of claim 4, wherein the analysis unit is further configured to determine at least one of a difference between the transmission time of the resultant signal and a transmission time of a reference signal and a difference between the amplitude of the resultant signal and the amplitude of the reference signal. 6. The system of claim 1, wherein the frequency of the initial signal is about 0.48 teraHertz. 7. The system of claim 1, wherein the filter status comprises at least one of a capsule presence within the smoking article filter, a capsule absence from the smoking article filter, a proper insertion of a capsule into the smoking article filter, a defective insertion of a capsule into the smoking article filter, a proper capsule within the smoking article filter, and a defective capsule within the smoking article filter. 8. The system of claim 1 further comprising a rod-making apparatus including a capsule insertion unit configured to insert a capsule into the smoking article filter, wherein the sensor and the emitter are disposed downstream from the capsule insertion unit. 9. The system of claim 8, wherein the sensor and the emitter are disposed downstream of a tipping device configured to wrap a tipping material around the smoking article filter and a tobacco rod. 10. The system of claim 1 further comprising a defective smoking article filter removal device in communication with the analysis unit and configured to remove a defective smoking article filter when the filter status indicates at least one of a capsule absence from the smoking article filter, a defective insertion of a capsule into the smoking article filter, and a defective capsule within the smoking article filter. 11. A method, comprising: positioning a smoking article filter between a sensor and an emitter;emitting an initial signal having a frequency between about 0.1 teraHertz and about 10 teraHertz toward the smoking article filter with the emitter;linearly displacing the smoking article filter along a longitudinal axis thereof;rotating the smoking article filter about the longitudinal axis simultaneously with linearly displacing the smoking article filter while emitting the initial signal;detecting a resultant signal resulting from interaction of the initial signal with the smoking article filter while traveling therethrough with the sensor;determining a filter status based on the resultant signal; andoutputting an indicium indicative of the filter status. 12. The method of claim 11, further comprising focusing the initial signal perpendicularly to the longitudinal axis of the smoking article filter; and straightening the resultant signal. 13. The method of claim 11, wherein determining the filter status comprises at least one of determining a transmission time of the resultant signal and determining an amplitude of the resultant signal. 14. The method of claim 13, wherein determining the filter status further comprises at least one of determining a difference between the transmission time of the resultant signal and a transmission time of a reference signal and determining a difference between the amplitude of the resultant signal and the amplitude of the reference signal. 15. The method of claim 11, wherein the frequency of the initial signal is about 0.48 teraHertz. 16. The method of claim 11, wherein the filter status comprises at least one of a capsule presence within the smoking article filter, a capsule absence from the smoking article filter, a proper insertion of a capsule into the smoking article filter, a defective insertion of a capsule into the smoking article filter, a proper capsule within the smoking article filter, and a defective capsule within the smoking article filter. 17. The method of claim 11, further comprising inserting a capsule into the smoking article filter, wherein emitting the initial signal and detecting the resultant signal occur after inserting the capsule into the smoking article filter. 18. The method of claim 17, further comprising wrapping a tipping material around the smoking article filter and a tobacco rod, wherein emitting the initial signal and detecting the resultant signal occur after wrapping the tipping material around the smoking article filter and the tobacco rod. 19. The method of claim 11, further comprising removing a defective smoking article filter when the filter status indicates at least one of a capsule absence from the smoking article filter, a defective insertion of a capsule into the smoking article filter, and a defective capsule within the smoking article filter.
