Spray Imaging

LaVision‘s SprayMaster inspex systems measure spray pattern and spray plume geometries of spray and aerosol generating devices. The light sheet based imaging systems use eye-safe LED lamps for illumination or lasers in case of very fast pulsed sprays.

High performance multi-cone fuel sprays up to single cone household sprays are tested in-line or on-line with automated spray parameter recording and test protocol generation. Axial spray profiles are recorded applying shadow imaging when a line-of-sight arrangement is better suited for a given spray test arrangement. The highly reliable imaging modules are field changeable following the highest industrial standards. The modular system design allows flexible solutions for even demanding customization requirements.

A comprehensive spray image analysis software tool kit generates in real-time process relevant data from the spray image, builds up a statistical data base, executes a quality criteria for spray acceptance including a feedback signal to the production/process line together with a customized test protocol for data traceability. Algorithmic based spray image processing guarantees fast, repeatable and operator independent results.

Global spray imaging on a light sheet can be combined with local droplet size and velocity measurements at a predefined location within the light sheet. Such a combined spray pattern and spray droplet imaging system for a comprehensive spray nozzle test is shown as an example of a highly integrated spray imaging solution.
