Abstract
A system and method for unobtrusively and non-invasively subjecting a human subject (10) to tests for the purpose of determining whether that subject is truthful and/or is under stress. A series of laser or infrared pulses (18) are directed to the human subject(10). These pulses are reflected or scattered (20) from the individual and are received by a receiver device (14). The receiver device (14) is connected to an information processing device (16) capable of determining various physiological characteristics exhibited by the human subject (10). A display (24) associated with the information processing device (16) would visually illustrate these physiological characteristics.
Claims
AMENDED CLAIMS
[Received by the International Bureau on 22 SEP 2003 (22.09.03) ; original claims 1 and 16, amended]
1. A system for non-invasively conducting polygraphic tests for determining the existence of stress on a human subject, comprising: a transmitter provided at a distance from the human subject for producing a plurality of coherent radiation pulses directed at the human subject; a receiver provided at a distance from the human subject for receiving reflected or scattered radiation pulses from the body or face of the human subject, said reflected radiation pulses including a measurable frequency shift between said coherent radiation pulses and said reflected radiation pulses, said measurable frequency shift and said scattered radiation pulses containing information relating to a plurality of physiological characteristic indicative of stress or the truthfulness of the human subject; and an information processing device in communication with said receiver for processing said measurable frequency shifts and said scattered radiation pulses.
2. The system in accordance with claim 1, further including a display device for displaying an output of said plurality of physiological characteristics.
3. The system in accordance with claim 2, wherein said plurality of physiological characteristics displayed by said display device includes at least one of the human subject's respiration rate, heart rate and temperature.
4. The system in accordance with claim 2, wherein said plurality of physiological characteristics includes the human subject's perspiration and said information processing device includes a spectral analyzation device for determining the existence of perspiration on the human subject's body.
5. The system in accordance with claim 2, wherein said information processing device utilizes said plurality of physiological characteristics to produce a single output displayed on said display device indicative of the truthfulness of the human subject.
14. The system in accordance with claim 1, wherein said transmitter produces a plurality of infrared pulses.
15. The system in accordance with claim 1, wherein said transmitter and said receiver are co-located.
16. A method for non-invasively conducting polygraphic tests for determining the existence of stress on a human subject, comprising the steps of: producing a series of coherent radiation pulses from a transmitter; directing said series of coherent radiation pulses toward a human subject provided at a distance from said transmitter; receiving reflected or scattered radiation pulses from the human subject by a receiver provided at a distance from the human subject, said reflected radiation pulses including a measurable frequency shift between said coherent radiation pulses and said reflected radiation pulses; and analyzing said measurable frequency shift and scattered radiation pulses to determine various physiological characteristics of the human subject which are indicative of the stress of the human subject and the truthfulness of the human subject .
17. The method of claim 16, including the step of establishing the distance between the human subject and said transmitter and said receiver.
18. The method of claim 17, including the step of establishing said transmitter and said receiver at the same location.
19. The method in accordance with claim 17, including the step of interrogating the human subject with questions during said producing and said directing steps.
20. The method in accordance with claim 16, further including the step of visually displaying each of said various physiological characteristics developed by said analyzing step.
