Beam Shift Film
Beam Shift Film
The operating principle of BS Film is based on the properties of uniaxial crystal. It is really small sized and easy applied in consumer electronic device.
As the video shows, Liqxtal’s beam shift device can shift the position of dot pattern in 4 steps by voltage control. We can control the position of projected pattern, therefore the depth information from different positions is captured to achieve a ToF (Time of Flight) camera with increased spatial resolution.
Features
- Electrically tunable with different steps
- RGB color supported
- Customized optical design
Application
- Virtual reality display – resolution enhanced for near-eye display system
- Increasing dot no. of projector
