Real-Time Sensor Outputs for True Measurement Implementation

While many industrial interferometric sensors are capable of measuring relatively large displacement velocities, most sensors lack high-resolution, high-speed digital position output interfaces. attocube has addressed this problem by providing a high-speed serial link (HSSL) which allows to output absolute displacement data with a true resolution of 250 pm and an output frequency of 400 kHz. This output is therefore perfectly suited for applications where highest precision combined with highest performance is required.

For industrial applications, attocube offers a real-time digital A-quad-B output interface which allows implementation of the metrology controller into complex industrial setups. With user-defineable step sizes and output frequencies, the A-quad-B output can be prefectly adapted to displacement velocity and resolution requirements. Position fluctuations faster than incremental step size times output frequency are low pass filtered.

> Incremental A-quad-B sensor outputs for industrial implementation
> 32 bit high-speed serial link (HSSL) for pm resolution at m/s target speed
> 32 bit low-latency USB output interface

	> Real-time, digital HSSL > A-Quad-B sensor output
With two A-quad-B interfaces seamlessly working together, a broad range of displacement velocities can be covered without the necessity to readjust the resolution of each output in case of a large variation in target velocity.
