Industry Applications
Particle Image Velocimetry (PIV) is a non-intrusive laser-based optical measurement technique used to accurately capture velocity field distributions in liquids and gases.
In a PIV system, the laser beam is delivered through a high-precision articulated optical arm, which flexibly guides the beam into the test section. After passing through optical conditioning components, the beam is shaped into a thin laser sheet that illuminates a measurement plane seeded with tracer particles.
A high-speed camera is positioned perpendicular to this plane to continuously capture particle images. By analyzing the displacement of particles between successive frames and combining it with the known time interval, the velocity of the particles is calculated. This process ultimately generates a full-field velocity vector map of the flow.
Beyond flow diagnostics, PIV-related optical delivery systems are also used in advanced scientific applications such as:
· Raman spectroscopy analysis
The laser is directed onto a sample to induce Raman scattering, enabling material composition and structural analysis.
In aesthetic laser treatments, the articulated arm delivers laser energy precisely to the skin surface for procedures such as:
· Pigmentation removal
· Tattoo removal
· Skin rejuvenation
· Skin tightening
The laser stimulates collagen regeneration and supports non-invasive cosmetic treatments.
In laser cutting systems, the beam delivery arm guides the laser to the cutting head for precision machining of:
· Automotive components
· Household appliances
· Non-metal materials
It enables stable, accurate laser transmission for high-efficiency industrial production.
