3D & Depth Techniques
Precision Measurement Beyond 2D Imaging
Depth measurement introduces geometric constraints that require careful optical design and synchronisation.
Accuracy depends on triangulation angle, calibration stability and motion control, not pixel count alone.

Laser Triangulation
High-accuracy surface and dimensional measurement using a laser line projected onto a surface to calculate height variation from geometric displacement. Enables micron-level measurement at production speed, perfect for railway wheel profiling, weld seam inspection, battery tab measurement and surface flatness analysis.
Typical Applications
- • Railway wheel profiling
- • Weld seam inspection
- • Battery tab height measurement
- • Surface flatness analysis
- • Inline geometric verification
Why It Matters
Triangulation enables micron-level measurement at production speed. Performance depends on mechanical stability, optical alignment and synchronised motion.
Typical System Elements
- • Laser triangulation sensors
- • Motion stages or robotic scanning platforms
- • Synchronised acquisition systems
- • 3D reconstruction software

Light Field (Plenoptic) Imaging
Simultaneous capture of spatial and depth information by capturing directional light data, enabling depth extraction from a single exposure without scanning motion. Ideal for robotic guidance, fast-moving object inspection, pick-and-place verification and compact automation cells.
Typical Applications
- • Robotic guidance
- • Fast-moving object inspection
- • Pick-and-place verification
- • Inline dimensional checks
Strategic Advantage
Depth extraction without mechanical scanning enables compact integration into automation cells. This is a differentiating capability for space-constrained systems.

Multi-Plane / Dual-Focus Imaging
Simultaneous capture of multiple focal planes using beam splitting or optical path offsetting. Eliminates mechanical refocusing and increases inspection reliability in dynamic systems, perfect for stepped components, transparent materials, layered inspections and compact, high-speed production environments.
Typical Applications
- • Inspection of stepped components
- • Transparent or layered materials
- • High-speed inspection where refocusing is not possible
Why It Is Valuable
It eliminates mechanical refocusing and increases inspection reliability in dynamic systems. This technique is particularly suited to compact, high-speed production environments.
