Blind field tests for the Fido explosives detector first took place at a DARPA facility at Ft. Leonard Wood, MO in order to evaluate the performance of the device compared to that of trained canines. During the trial, landmines were planted in the test field with two flags approximately 50 cm apart indicating

1368-466: The Fido explosives detector were engineered to be preferentially responsive to nitroaromatic explosives. The binding of the TNT molecules is believed to be caused by an electrostatic-type interaction between the polymer and the target analyte. Selectivity can also be improved by synthesizing structures into the polymer that are electrostatic mirror images of the desired target analytes. According to reports, there

1425-560: The U.S. Navy Office of Naval Research's Chemical Sensing in the Marine Environment (CSME) program, becoming the first to demonstrate the mapping of an explosive plume underwater in real time.

1824-511: The device to sample 1 liter of air without the enhancement. This new addition made it possible for the device to detect the source of the vapor without having the sensor come in physical contact with the contaminated item. Throughout its continued development, the Fido explosives detector underwent numerous modifications by the U.S. military to be mounted on various types of platforms in order to detect traces of explosive vapors in dangerous environments and hard-to-reach areas. One prominent example

1881-435: The field test took place throughout the duration of the experiment. The results of the study demonstrated that both the Fido explosives detector and the MEDDS were both able to detect explosive vapor at the test site even as the months passed and field conditions changed drastically. However, there were no discernable patterns or any correlation between the sampling results of the two detector systems. The study also found that

1938-538: The field tests, DARPA verified that the performance of the Fido explosives detector was at a level equal to or better than that of the trained canines, marking the first time that an electronic “sniffer” device demonstrated a landmine detection ability comparable to that of trained canines under field conditions. In 2001, researchers sponsored by the Army Communications Electronics Command, Night Vision and Electronic Sensors Directorate conducted

1995-415: The fluorescence of entire polymer chains in the thin film, thereby amplifying the effect of a single TNT binding event that may bypass the detection of less-sensitive molecular sensors.

The test field on which the experiment took place featured 8 to 15 individual landmines (PROM-1, TMA-1A, PMA-2, and PMA-3) randomly distributed at 10, 15, or 20 cm beneath the surface. A separate test field was established adjacent to the primary test field to determine how far trace levels of contamination could be detected from a mine. Multiple sampling trials of

2166-492: The invention of the amplifying fluorescent polymer (AFP) in the late 1990s. At the time, the use of fluorescent polymers in their solid state was difficult due to their significantly decreased sensitivity and fluorescence compared to polymers in solution. In 1995, chemist Timothy Swager at the Massachusetts Institute of Technology (MIT) was the first to demonstrate the possibility of sensory signal amplification using

Three different teams were tasked with detecting the buried landmines at each test position. One featured the use of the Fido explosives detector and the other two were experienced teams of canines, one trained to detect explosives (i.e. bombs) and

2280-451: The mine locations while sensor responses within the mine lanes were frequent despite the fact that the mine signatures can travel significantly far from the center of a mine. The researchers also found that the intensity of the sensor responses increased after a night of light rain. The study concluded that while the Fido explosives detector may have difficulty with identifying the exact location of buried landmines, it may be useful in detecting

2337-456: The mine signatures, it was unable to precisely pinpoint the exact location of the mines in the lanes with any degree of certainty. The researchers concluded that the device's performance was due to high density of mines in the lanes which caused the chemical signatures from the mines to overlap each other, making it difficult to pinpoint the mines’ exact location. However, the Fido explosives detector produced fewer sensor responses in areas away from
