People often refer to the polygraph as a “Lie Detector.” The term polygraph means many writings. The forensic term is “Forensic Psychophysiological Detection of Deception (PDD)”.
 
The polygraph records autonomic arousal and physiological responses to a series of questions presented to an individual by a qualified examiner using a validated / approved testing format. The examiner is then able to decipher the chart polygrams and render a diagnostic opinion as to the veracity of the subject being tested. During the polygraph examination the following activity is simultaneously and visually monitored / recorded.
 
1. Respiratory (breathing) patterns using pneumographs.
2. Blood pressure and pulse rate (cardiovascular activity) using a blood pressure cuff.
3. Electrodermal or galvanic skin response is measured through electrodes attached to an examinee’s fingertips or use of disposable solid gel electrodes attached to the hand.
 
The three common phases of the examination process are the Pre-Test Phase, In-Test Phase and Post-Test Phase. Properly conducted, an examination should take a minimum of 90 minutes.
