Oxford Lasers Imaging Division produces high-speed imaging systems for particle, droplet and bubble size measurement, spray pattern analysis, and flow visualization. Our advanced systems let you see what's really happening.


Spray Droplet and Particle Size Measurement

Spray droplet sizing in a paint spray

When you need to measure the size and shape of your particles, droplets or bubbles, turn to image based analysis for size distribution measurement. Our 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. In addition to measuring the particle diameter distribution, Oxford Lasers imaging systems also provide shape and velocity analysis.  read more »

Spray Pattern and Plume Geometry Measurement

Envision- spray pattern

Spray Pattern Measurement Systems are used for characterization of many types of spray including: nasal / MDI (metered dose inhaler), 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)

PIV 2d Fluid Flow Vector Map

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 »
