Company History

In October 1976, the semiconductor manufacturing facilities and processes were sold to Carson-Alexiou Corporation, Irvine, California, later becoming part of the Magnavox Corporation. Detection Sciences Group became independent of ADL in 1976, and Mr. Stanfill became the Sole Owner of Detection Sciences Group. The company continued to do research and consulting in advanced infrared and electro-optical systems for applications such as advanced surveillance satellites. In 1979, DSG began working with ground-penetrating radar (GPR). Starting with a commercially available GPR system (GSSI SIR System-8), DSI began an internally-funded research and development program for custom designed, high performance, high resolution GPR equipment to support the Company's survey activities. DSG incorporated a wholly owned subsidiary, Detection Sciences Inc. (DSI), for the purpose of performing geotechnical surveys for clients. Over the years, DSI has accumulated thousands of man-hours of scientific investigations on hundreds of field sites. This scientific work with GPR led to the discovery of Electromagnetic Radiography (EMR)™ in 1991.¹ DSI has continued to design and develop special purpose survey equipment, including the design and development of the very high performance Electromagnetic Radiography (EMR)™ systems used to identify specific molecules and elements in the ground with detection capability in the low parts-per-billion (µg/kg) range.

Over the past 26 years, the bulk of the Company's survey work has been in the area of hazardous waste sites, including Superfund sites. Most of these surveys involve the detection of low level chemical contamination in the ground, as well as solid waste, and the geologic assessment of the subsurface conditions. More recently, attention has been focussed on the assessment and exploration of mining, petroleum and other natural resources, including gemstones. The same sophisticated techniques that allow specific chemicals and elements to be identified and detected at very low concentrations also apply equally well to non-hazardous substances and natural resources. Along with the ability to look directly into the ground and generate high-resolution holograms of specific ground contents, DSI now has the ability to perform slant-range surveys in a manner similar to side-scan sonar. Together, these technologies make it possible to perform wide area surveys with unprecedented precision and accuracy and to specifically identify minerals, metals, gemstones or other resources such as petroleum, hydrocarbons and coal.
