how a microV™ works

Introduction

If even the relatively small miniLDV is too large for your application, MSE's microV may be the perfect fit. Frequently used with traverses in small places or directly embedded into the hulls of models and full scale vessels, this unique sensor uses holographic beam shaping technology to enable the world's smallest "time-of-flight" sensor.

A "time-of-flight" sensor measures velocity by timing the occurrence of two events. In the case of the microV, these events are the crossing of two distinct miniature laser sheets by a particle. By knowing the spacing between the laser sheets in physical space, the velocity can be calculated by the simple relationship velocity = distance / time.
