The ultraLDV is the first of the next-generation probes from MSE featuring an all-inclusive probe body, proprietary hardware processor (Processing Engine) with USB interface, laser, and receiving optics and electronics. As with the miniLDV, the ultraLDV is pre-aligned and calibrated at the factory—no user alignment is necessary. The complete system is about the size of a shoe box.
The ultraLDV features larger receiver optics (4 to 9 times more light) and ultra-stable frequency shifting. It was designed from the beginning for extremely high stability and precision, making it ideal for measuring small velocity disturbances in flows.
