Solid State Video Module

Contamination Detection, Detailed Soil Classification:

Conventional geophysical sensors offer a general “picture” of soil composition and contamination, but cannot provide detailed information. VERTEK’s Video Module provides a high resolution view of the soil in real time, allowing the operator to visually detect or confirm the presence of non-aqueous phase liquid contaminants, such as creosote, coal tar, and gasoline. The Video Module also shows soil texture, grain size, color, and other features, reducing the need for expensive and time consuming soil sampling. Merging our existing hydrocarbon fluorescence technology into our video camera will allow users to identify the type of hydrocarbon contamination that they are viewing based on the color of the fluorescence. Users can also measure moisture content with our new IR illumination source.

Video Module System Description:

The Video Module integrates a miniature color video camera, and 3 LED illumination sources; UV, IR, and visible warm light. The camera is housed behind a durable, scratch-resistant sapphire window and a standard CPT rod housing. A cable pass-through channel allows a standard CPT cone, FFD, or other modules to be configured ahead of the video unit.

Video and camera illumination control and data signals are transferred between the module and any DataPack 2010 via Vertek’s standard 10 conductor cable.

Video can be obtained through the analog output BNC port on the DP2010 or through the DP2010’s built in H.264 MPEG 4 video encoder.

The Text Inserter Module is easily connected to the DataPack 2010. The inserter places a depth "stamp", communicated from the DAS or computer, on the video images as they are recorded. The operator can easily write additional information, such as the date and test identification number, on the videotape. A color television, digital camcorder, VCR, or other devices connect to the DataPack 2010 output to provide real-time monitoring and recording of the video images.
