High-speed Imaging

High-speed cameras provide the ability to capture and play back videos of the spray process, which might happen too quickly to be evaluated in real time.

High-speed Imaging Overview
High-speed video of the spray process allows for evaluation of the transient spray characteristics, whether the area of interest is at the exit of the nozzle or near the spray target. Spraying Systems Co. uses an Olympus i-SPEED TR camera, which features a maximum frame rate of 10,000 fps, a user-friendly interface and a stand-alone video playback screen.

High-speed Imaging Benefits

High-speed imaging provides a unique view of the instantaneous spray distribution, concentration, shape and trajectory, and also allows for the assessment of very fast spray development. The image-based measurement makes the results mostly qualitative in nature, but the images are easily evaluated and provide a simple way to visualize the spray. However, the image’s field of view is limited, and because adequate background light is required, this instrument works best with light droplet density sprays.

High-Speed Imaging Method

The high-speed imaging system uses a high-sensitivity, custom CMOS sensor with a high shutter speed to acquire over 600,000 image frames per second. Images may be acquired at a maximum pixel resolution of 1280 x 800 (1 MP) up to 22,000 frames per second. High intensity lights are used to illuminate the spray plume and droplets using front or back-lighting.
