Particle, droplet and bubble size measurement, spray pattern analysis, flame and weld viewing and PIV. Our advanced systems let you see what's really happening.
Online Spray Droplet and Particle Size Measurement
Measure the size and shape of particle, droplets or bubbles with image-based analysis. VisiSize online droplet sizing systems capture high-speed images of a particle cloud, spray (e.g. for water droplet size measurement) or bubble stream to give the drop size distribution. In addition to measuring the particle diameter distribution, Oxford Lasers imaging systems also provide real-time particle velocity and shape analysis.

Spray Pattern and Plume Geometry Measurement
Spray Pattern Measurement Systems are used for characterization of many types of spray including: nasal sprays, MDI (metered dose inhaler), DPI (dry powder inhalers), agricultural, water, paint, fuel injectors and domestic aerosols. Spray patternation systems capture images of the spray and calculate its pattern, cone angle / plume geometry and time evolution. Optional software and hardware allow droplet size measurement and velocity measurement. read more »

Particle Image Velocimetry (PIV)
Particle Image Velocimetry systems are used for flow velocity measurements in liquids and gases. In addition to supplying conventional 2D PIV, stereo PIV, micro PIV and High speed (Time Resolved) systems, Oxford Lasers supplies stand-alone dual pulse and high repetition rate lasers, cameras and PIV software. These systems can also be used for flow visualization. read more »

Look Through the Blinding Welding Glare
Flame penetration imaging can be used to take movies through flames, arcs and explosions. When an arc or laser welding process is imaged with a normal imaging system, the high brightness of the plasma saturates the camera and no detail can be seen. VisiWeld systems eliminate the glare to give a clear image of the weld process. read more »
