The respective measurement capabilities are demonstrated by experiments. As a result, volumetric velocity measurements are obtained for 256 × 128 × 25 voxels over 14.4 mm × 7.2 mm × 6.5 mm with a repetition rate of 1 kHz, which allows the investigation of unsteady phenomena in sprays such as transients and local velocity oscillations. Volumetric data is finally obtained by slewing the laser light sheet in depth with an oscillating microelectromechanical systems (MEMS) scanner. This allows fast continuous planar measurements of the velocity. For this purpose, a spectroscopic technique is realized with a power amplified, frequency modulated laser and an Mfps high-speed camera. To investigate fast unsteady phenomena, e.g., in sprays, volumetric (3D) measurement techniques with kHz rate are required. However, those methods are either restricted by measuring pointwise or with low measurement rates of several hertz. Spectroscopic methods are established tools for nonintrusive measurements of flow velocity. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.
Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".With exceptional light sensitivity, excellent image quality and flexible region of interest (ROI), the Mini AX is available in 3 models - Mini AX50, Mini AX100 and Mini AX200 - respectively delivering 2000 fps, 4000 fps and 6000 fps at a resolution of 1024 x 1024 pixels (1-megapixel sensor).
