The LSPP laser scanning profilograph- profilometer is a highly sensitive measuring device to define surface roughness and defects of machine components made of steel, cast iron, non-ferrous metals and alloys, as well as non-metallic components and other surfaces without damaging and destroying them.
This new prospecting non-contact measuring device is a part of the contemporary and dynamically developing class of devices. Its major advantages are:
- high depth sensitivity (to 1 nanometer) and highly vibro-protective surface investigation speed.
- Laser beam scanning across the selected line or in raster-scan regime.
- Side examination of inside holes (not less than 10 mm in diameter)
- Three-dimensional computer scan of the examined surface.
The device provides:
- reliable information on various objects in reflected, transmitted and scattered radiation;
- the so-called photo-related and phase-differential photo scans, which are world-known, but insufficiently explored; this gives excellent opportunities for research study.
Acoustic-optical scanning of objects (non mechanical) by two laser radiation beams splitting into two orthogonal directions provides three-dimensional phase-differential scans. This method also allows to obtain two-dimensional phase-differential information on object surface by using 2D acoustic-optical fast-response devices for laser radiation control.
Laser profilographs and profilometers have module design and vary in structure and set of tools depending on the field of application and purposes.
