Koncerto PIV Overview

PIV is one of the so-called Time of Flight (TOF) measurement techniques. The basic principle of the PIV is that a laser light sheet is used to illuminate the flow field which is seeded with small particles to visualize a flow to be measured. A double pulse YAG laser and a double shutter camera are synchronized to record two particle images with very short time separation, typically less than 100 us.

Stereo 3D PIV

Koncerto supports several types of stereo calibration target such as a single height double side with traverse type, a double height double side with common lower plane no traverse type, etc.

Distributed processing and Automated processing

Koncerto supports distributed processing and script programming. These are especially useful for handling large amount of data such as Time Resolved PIV. With the sophisticated high speed PIV processing algorithms, Koncerto processes a large amount of data in a short time automatically.

Various output data format

Captured images and analyzed data can be saved and output in various formats.  For example, output PIV data to a data visualization software such as Tecplot, and sliced images on micro imaging are transferred seamlessly to a volume rendering software..

Various output data format

Online multi view window enables you to monitor both A and B images at the same time.

Various output data format

Online Scatter View is useful for checking several PIV parameters such as the image quality, delta T, the intensity of validation filters, etc.

Various output data format

Online PDF View is useful for evaluating the intensity of peak locking, etc. It is one of the criteria for choosing the PIV analysis algorithms.

Various output data format

Timing View is used for setting the hardware timing such as delta T and various delays.
