GPR : Mapping Subsurface Structures
Ground Penetrating Radar (GPR), also known as Subsurface Imaging, is a sophisticated geophysical technique used to detect subsurface structures without disturbance. It utilizes high-frequency electromagnetic pulses that are transmitted into the ground. These signals reflect back to a receiver, providing information about the position and composition of subsurface objects.
- Various applications of GPR include:
- Identifying underground utilities
- Analyzing geological formations
- Examining archaeological sites
- Observing voids and cavities
The interpretation of GPR data typically necessitates specialized software and expertise to create accurate subsurface maps.
Thermal Imaging: Visualizing Heat Signatures
Thermal imaging depicts the invisible world of heat. This technology utilizes infrared radiation emitted by objects to generate a visual representation of their temperature variations. By detecting these thermal signatures, we can observe patterns and anomalies that are invisible to the naked eye.
Thermal imaging finds uses in a wide spectrum of fields, including medical diagnostics, inspection, and even ecological research.
