RP-I brain wave lie detecting system is designed by adopting the most advanced scientific research results, with characters of easy operation, stability and reliability. It is applicable in various criminal investigation, economical investigation and judicial authentication organization. It is a model of the new generation of lie detectors due to its management system of powerful automatic analysis, survey and statistic.

Testing Theory: It uses the event related potential detecting, no influence of the testee’s subjective purpose, which is the most advanced technique of lie detecting.  Especially it uses the image stimulating technique, which provides an impersonal visual space, drawing the testee’s recall and cognizing of past event, recurring the past and accurately detection. It is easy to investigate various crime scenes, especially for the testees with physical defects such as deaf-mute, it is also valid.

It is designed into portable type, based on the Win XP/2000 operation system, with a high stability.
USB mouth, digital double channel and electric potential collector, brain wave signal is put into the computer after digital processing. Powerful anti-disturbing ability can secure the true brain wave. As well, the sampling rate of 1000 points/second can’t be controlled by human’s subjective will, so there is no false positive rate.

During the period of stimulating image, the start point can be chosen freely to meet the demand of various detections. Brain wave record adopts special averaging technique and chooses freely averaging manner. Disturb due to non-cooperation of the testee can be eliminated.

Synchronous monitoring system can record and recurring the monitoring image and brain wave signal synchronously, and monitor the cooperation of the testee. This is favorable for observation and avoiding anti-detection, confession withdrawal and false charge etc. 

Target and non-target averaging result wave: can magnify and minify amplitude and sensitivity to make the wave contrast more clear; wave area and latent period, amplitude, mark, survey and calculation can automatically realize; stimulating graph and brain wave graph can display correspondingly, leading to a easy result. Experts automatically analysis system makes various functions very clear and simple.
