Experience the benefits of active markers
The Intelligent Active Marker System is unrivaled in speed, precision and flexibility.
fastest on earth
Real-time motion capture system

No other motion capture system comes close to the Impulse X2E capture rate of 960 frames per second at up to 13MP resolution. This means you don't have to choose between speed and resolution. You can get the best of both worlds. Whether it's virtual reality entertainment or biomechanical engineering, the most demanding customers rely on PhaseSpace for superior speed and precision.

The Impulse X2E system captures at a stunning 36,000 x 36,000 sub-pixel resolution in HDR. (1,300 MP) That's about 100x the resolution of most motion capture cameras. What's our secret? Like other mocap systems, it uses a custom linear detector instead of an RGB camera. This equates to the highest tracking accuracy at full speed. (down to 20µ at 960Hz)
