MEMS Sense Tester (GTS)

MEMS Sense Tester - Ground-truth station (GTS)

When developing MEMS or a MEMS based product, it is critical to characterize the MEMS position sensing capabilities in all working conditions.

This crucial phase allows you to improve both the hardware and the controller of the MEMS to get the best performance.

ARCYTEC's MEMS-experts identified the need for an accurate and automatic MEMS Scanner Tester that enables repetitive and high precision test cycles. We have managed to develop an innovative Ground Truth Station - compact and fully automatic MEMS Scanner Tester.

When characterizing the mems sensing and driving capabilities there is no better way to test the accuracy and precision of the MEMS sensing / positioning than have an automatic tester designed to do just that.

Main Specifications

The GTS MEMS Test-bench was developed to allow 2 levels of test accuracy, depending on the MEMS sensing accuracy you require.

GIMBAL A - LEVEL OF ACCURACY ±0.14 mrad
GIMBAL B - LEVEL OF ACCURACY ±0.024 mrad

The standard Tester can support large devices up to 30cm (11.8 inch) and 15kg (33 lbs) but it can easily be adapted to support various sizes / on demand.

The GTS software is uniquely designed to support REPETATIVE and AUTOMATIC testing. These feature enable FAST and REPETATIVE data collection on several samples and therefore it simplifies the characterization process.

Thermal Feature

One of the most unique features of the GTS is the Thermal unit.

Position sensing performance for scanning devices can vary over temperature.

TEC can be used to regulate temperature and test the sense performance at different temperatures.

The top Gimbal plate can be used for thermal coupling between the UUT and TEC.

Device mounting base

Device mounting base is designed to support several instruments along with the actual UUT:

  • Alignment device
  • Validation device
  • Thermal unit
  • UUT device

Mounting base might need to be customized if a relatively different form-factor device will be used on the bench.

Mounting base supports thermal conductivity between Peltier & UUT.

ARCYTEC's experts are at your service and can customize the station to fit your product's needs.
