Our FE-1 shutter goggle design utilises ferroelectric liquid crystal (FLC) technology. This provides:

  • 100 µs switching times
  • 3-log unit contrast ratio
  • 25% open shutter transmission

FE-1 Goggle

The performance of LCD-type shutters, particularly the closed state transmission, is affected by temperature. Our shutters are specially manufactured to operate at 24°C for optimum performance. Most off-the-shelf FLC devices are quite small. Therefore our custom shutters have an extra large aperture to provide a good field of view. The adjustable goggle mounting can be worn over normal spectacles, and is electrically isolated for subject safety.

The FE-1 goggles are driven directly by the ViSaGe in synchrony with its monitor configuration. A digital output is concurrently available to trigger a data acquisition system or other external equipment. The CRS MATLAB Toolbox includes full support to control the individual shutter states for complete experiment control. A secondary output allows you to observe the test using a pair of low-cost LCD or similar shutters.
