Through the software processing of IRIS-M , a video of the equipment vibration is taken with a high-speed camera, and continuous changes of each pixel are analyzed. Its amplitude is amplified dozens of times. The user can immediately see and observe its vibration mode. Compared with traditional modal/ODS test analysis technology, it is more intuitive and faster. IRIS-M can even extract the vibration waveform, amplitude, spectrum, phase angle and other data of the specified position in the video.
