FtrTSPIV is an efficient full-volume PIV system that utilizes the new technology of Tomographic Stereo PIV (patent pending). It features high-speed data analysis and a lightweight data capacity, and can be easily expanded from the well-received Stereo PIV (FtrPIV-Stereo). ■ High-speed analysis and compact data capacity The three-dimensional brightness distribution reconstructed with MART had a significantly larger data volume compared to the original image data. However, with the development of multi-slice Stereo PIV technology in FtrTSPIV, the data volume has been reduced by more than one order of magnitude compared to conventional TomoPIV, and the analysis speed has increased by more than one order of magnitude. It also exhibits performance that surpasses conventional TomoPIV in terms of analysis accuracy and stability. ■ User-friendly system integration "Tomographic Stereo PIV" is software developed for comfortable full-volume measurement. After the reconstruction of the three-dimensional brightness distribution and the generation of the back-projected images for Stereo PIV, Stereo PIV is performed on the back-projected images using the fluid image analysis software "FtrPIV." This integration allows all data analysis to be performed with simple operations.

• Other measurement, recording and measuring instruments

An important physical quantity that represents the characteristics of dispersed two-phase flow is the information on the individual particle diameter and velocity. FtrPIA (Particle Image Analyzer) is a particle measurement system that utilizes background illumination and direct imaging. It is capable of visualizing and quantifying everything from the particle formation process to the flight conditions, making it powerful for understanding the characteristics of dispersed two-phase flow. PIA (Particle Image Analyzer) is a method that measures particle diameter and velocity by magnifying and capturing images of flying particles using microscope lenses and analyzing the particle images. Its advantage is that it can measure regardless of whether the particles are spherical/non-spherical, transparent/opaque, or solid/liquid. The measurement accuracy is determined by the spatial resolution of the imaging device and the resolution of the optical system used for imaging. The FtrPIA system includes FtrPIA-TCL, which solves the depth of field problem, and FtrPIA-Endoscope for measuring dense particle groups.

• Other embedded systems (software and hardware)

The FTR high-speed photodetector is a compact laser waveform observation device that employs a broadband Si PIN photodiode. It features high-speed response, wide wavelength compatibility, and a small, lightweight design. By connecting the output terminal of this device to a broadband oscilloscope and directing weak reflected laser light into the input section, the laser pulse emission waveform can be observed in real-time. When there are two laser emissions with a time difference Δt, the FTR PIV analysis software can automatically calculate Δt from the emission waveform data measured with this device and the broadband oscilloscope. Furthermore, since the measured Δt obtained from the emission waveform data is matched one-to-one with the camera image data, accurate PIV calculations can be performed using precise Δt values.
