System selection

Muon imaging systems

Choose a detector around your target, available access and measurement time. Geoptic’s systems use naturally occurring cosmic-ray muons to investigate density variations without introducing an artificial radiation source.

Find the right deployment format

Atlas

A configurable, large-area detector system for non-invasive imaging of structures and the ground around them. Multiple detector modules provide broad coverage from accessible survey positions.

When to consider it

Accessible survey positions where broad coverage and limited site access time are important.

Typical applications

Railway tunnel assessment, including investigation of voids behind linings
Underground construction monitoring and geotechnical surveys
Structural investigations targeting density anomalies and material loss

View system details →

Prism

A compact, modular muon imaging system for detailed density measurements in confined environments. Individual units support targeted investigations, while multiple units can form arrays for broader coverage.

When to consider it

Restricted spaces and targeted investigations where a compact detector can be positioned near the region of interest.

Typical applications

Localised void and density investigations in tunnels and mines
Assessment of concrete, rock and composite structures
Continuous monitoring and distributed multi-detector deployments

Strata

Slimline detectors lowered into boreholes to investigate deeper subsurface features. Detectors can be connected in a string, with shared power and communications linked to a surface data-acquisition node.

When to consider it

Subsurface targets where a suitable borehole provides a measurement position that surface access cannot offer.

Typical applications

Borehole-based subsurface density investigations
Downhole deployments in water-filled or demanding environments
Multi-depth detector strings for extended subsurface investigations

Deployment considerations at a glance
Selection factor	Atlas	Prism	Strata
Size / form factor	1.4 m × 1.2 m area	391 mm × 307 mm footprint; 3 kg	60 mm diameter; 2.2 m length
Access requirements	Space for a large detector array at an accessible measurement position	Confined or accessible positions in or around the region of interest	A suitable borehole, cable route and surface equipment position
Best-fit starting point	Accessible survey positions where broad coverage and limited site access time are important.	Restricted spaces and targeted investigations where a compact detector can be positioned near the region of interest.	Subsurface targets where a suitable borehole provides a measurement position that surface access cannot offer.
Measurement planning	Consider when site access time is constrained; acquisition time still depends on the target and geometry.	Suitable for monitoring where a detector can remain deployed; arrays can increase measurement speed.	String length and detector count are selected for depth, geometry and required acquisition time.

These are starting points for selection, not guaranteed performance limits. Achievable resolution and acquisition time depend on target size, density contrast, material thickness, detector position and the available muon flux. A feasibility assessment establishes whether the proposed geometry can answer your investigation question.

What to tell us about your investigation

You do not need to choose a detector before contacting us. Share what you know, and we can assess the appropriate system and deployment approach.

Target and decision: what you need to locate or monitor, its approximate size and the decision the results must support.
Structure or ground: material, thickness or depth, drawings and any existing investigation data.
Access: possible detector positions, available space, borehole dimensions and site restrictions.
Timing and services: access windows, possible deployment duration, power and communications availability.
