Lineprobe

Lineprobe is a generic term used to describe a device or method that samples, interrogates, or measures signals or properties along a single straight line. It is employed across multiple disciplines where high-resolution data along a linear path is advantageous, such as electronics, imaging, sensing, and surveying.

In electronics and sensing, a lineprobe often refers to a line-scan or contact probe that engages points along a line of a circuit or surface to measure parameters like impedance, resistance, voltage drop, or continuity. When combined with precise motion stages, lineprobes can generate line-based maps of electrical or physical properties, enabling rapid inspection of boards or components.

In imaging and spectroscopy, lineprobes can denote line-scan sensors or line-probe assemblies that capture spatial or spectral information for one dimension. By sweeping or moving the line across a target, they build two-dimensional images or spectra with high line resolution, useful in industrial inspection, document scanning, or microscopic analysis.

In non-destructive testing and field surveying, lineprobes are used to detect material variations, hidden features, or subsurface conditions along a defined trajectory. Techniques may include contact or non-contact methods such as ultrasonic, infrared, or eddy-current based sensing, depending on the application.

Operational factors for lineprobes include precise alignment, calibration, synchronization with motion control, and appropriate data processing. The main advantages are fast, high-resolution sampling along a line; the main limitation is the narrow field of view, requiring multiple passes for broader coverage.
