3D smart measurement
1. The main controller uses a very large - -scale integrated 32- bit embedded ARM-M7 core processor as the core control unit, and the main clock frequency is 200MHz; the coprocessor uses Intel' s FPGA highly integrated programmable digital signal processor;
2. Purchasing a modular structure, the core computing module of the main board, a single control module for motor control, and an independent module for computing control, which are convenient for installation and debugging, and work stable and reliable;
3. Brand-new light path design, high- defnition imeging effect, smooth picture, good customer experience;
4. Using stepper motor control interpolation algorithm, pupil tracking response is fast, tracking position is accurate, eye position can be automatically memorized, re-measurement does not need to fnd eye again, you can quickly go to the eye position based on the last recorded position, and quickly repeat the measurement;
Specifcation
◆ Main technical data, the data measurement result is accurate, stable, and fast ;
◆ Date transfer: RS232(Standard equipped), Bluetooth, VGA and WIFI(Optional)
