Laser sensors measure distance to or the displacement speed of a target.
These devices are found in automated manufacturing, conveyance systems, positioning and alignment of workpieces in mechanical fabrication, for processing and packaging, on electronic component assembly lines, in agribusiness and automobile manufacturing.
Such sensors use a laser diode to emit an intermittent, fixed- or adjustable-width light beam, or illuminate part of a space. A CCD sensor reads the reflected light by optical convergence. Target distance is calculated by triangulation.
Speed and displacement sensors use this same method, but the Doppler effect is more commonly employed in laser telemetry. Here, the phase shift between the emitted and the reflected signal indicates the relative speed of the target object.
More powerful thermopile or cooled sensors have a range of up to several hundred meters. Otherwise, range is usually under one meter, or several dozen meters in the case of long-range devices.
Blade counting models measure the speed of objects with discontinuous reflective surfaces, such as a spinning fan.
Choice will depend on sensor resolution, range and data acquisition speed.
