Carlson Void Scanner+

Carlson Void Scanner+

The Carlson Void Scanner+ is a high-precision geophysical survey tool designed for underground scanning and mapping. It is used primarily in geological, mining, and environmental applications to detect voids, cavities, and anomalies beneath the surface, such as underground tunnels, sinkholes, or abandoned mine shafts.

The scanner employs a variety of geophysical methods, typically ground-penetrating radar (GPR) or other radar-based technologies, to generate detailed images of the subsurface. The device provides high-resolution data that can help engineers, surveyors, and geophysicists to assess the stability of underground structures, locate potential hazards, and plan excavation or construction projects safely.

Features:

• Advanced radar technology for detecting subsurface voids and cavities.
• High-resolution imaging for clear and accurate results.
• Portable design for ease of use in the field.
• Data logging and analysis software to interpret the results and generate reports.
• Real-time feedback for immediate decision-making during surveys.
• Compatibility with other surveying tools and equipment.

Applications:

• Infrastructure Assessment: Evaluating the condition of bridges, roads, and tunnels.
• Utility Location: Identifying and mapping underground utilities to avoid damage during construction.
• Geological Surveys: Analyzing soil and rock layers for mining and environmental studies.

Benefits:

• Accuracy: High-resolution imaging for precise void detection.
• Safety: Identifies potential underground hazards to reduce risk.
• Cost-Effective: Faster surveys with no need for excavation or drilling.
• Non-Destructive: Surveying is non-invasive, preserving the integrity of the site.
• Real-Time Data: Instantaneous results enable quick adjustments in the field.
• Versatility: Suitable for a variety of industries and applications.
• Portability: Easy to transport and operate in various environments.

Specifications :

1. Radar Frequency

• Frequency Range: The device typically operates in the 100 MHz to 2 GHz frequency range, which allows for high-resolution scanning at various depths. Higher frequencies provide better resolution but less penetration, while lower frequencies penetrate deeper but offer lower resolution.

2. Scanning Depth

• Penetration Depth: The Void Scanner+ is capable of detecting subsurface anomalies at varying depths, with typical penetration ranges between 5 meters (16.4 feet) to 30 meters (98.4 feet) or more, depending on soil composition, frequency setting, and environmental conditions.

3. Resolution

• Vertical Resolution: The vertical resolution is typically in the range of 2 cm to 10 cm (0.8 inches to 4 inches), depending on the frequency and depth of the scan.
• Lateral Resolution: The lateral resolution can be around 5 cm to 20 cm (2 inches to 8 inches), again depending on the scanning frequency and scanning depth.

4. Data Acquisition

• Real-Time Imaging: The system allows for real-time data visualization during the scan. The user can view 2D radar profiles and, in some cases, 3D maps of the subsurface structures.
• Data Logging: High-capacity storage for capturing extensive data during field surveys, with options to store data in standard file formats (e.g., CSV, DXF, or proprietary format).

5. Operating Environment

• Temperature Range: Operates in a wide temperature range, typically from -10°C to +50°C (14°F to 122°F), allowing for use in both cold and hot environments.
• Weather Resistance: Designed for rugged field conditions, with IP67 or higher ingress protection, meaning it is dust-tight and resistant to water immersion (up to 1 meter depth for 30 minutes).
• Power Supply: Often powered by rechargeable lithium-ion batteries, with typical operating times of 6–12 hours depending on usage and battery capacity.

6. Interface and Software

• User Interface: The scanner features an intuitive touchscreen display for real-time data monitoring and navigation.
• Data Analysis Software: Comes with proprietary software for data interpretation, 2D and 3D mapping, and generating detailed reports.
• Connectivity: Features connectivity options like USB, Wi-Fi, or Bluetooth for transferring data to a computer or cloud service for further analysis.

7. Dimensions and Weight

• Size: The scanner is designed to be portable, typically weighing around 5-12 kg (11-26 lbs) depending on the model and accessories.
• Compact Design: It is built to be compact and lightweight for easy transport and operation in the field.

8. Scanning Modes

• 2D Profiling: Allows for vertical cross-sectional imaging of subsurface voids and anomalies.
• 3D Imaging: Some models of the Carlson Void Scanner+ are capable of generating 3D visualizations of the subsurface, which provide a more comprehensive view of detected voids.

9. Signal Processing

• Advanced Signal Processing: The scanner uses advanced signal processing algorithms to enhance the clarity and accuracy of the data. This might include features like time-domain reflectometry (TDR) and frequency-domain analysis to improve depth penetration and resolution.
• Noise Filtering: The system may have built-in filters to minimize noise interference from environmental conditions like moisture, rocks, or metal objects.

10. Applications

• Mining and Geotechnical: Detects voids and cavities in mining operations, including abandoned shafts or tunnels.
• Construction and Infrastructure: Identifies underground voids that could affect construction projects.
• Environmental Monitoring: Detects potential environmental hazards, such as sinkholes or contamination plumes.
• Archaeology: Used for non-invasive exploration of archaeological sites.

Features:

• Easy Mobility: The scanner is typically portable and may come with a rugged carrying case for transport.
• Data Interpretation: The software provides tools for data visualization and interpretation, helping operators quickly assess void locations and characteristics.
• Multi-Sensor Integration: In some versions, the Void Scanner+ might allow integration with other geophysical tools like magnetometers or GPS for more comprehensive surveying.
