Prolonged field trial

The control software was redesigned to allow for a shut percentage (duty cycle) of the electrical waveform to be set. This is useful for slower LCD shutters that require a significant fraction of a 31.25 ms half wave period to fully reopen after being in the closed state.

Limited field trial

This is the first version whose operation was tested over periods of many hours. While field trials may start, further improvement of the software and validation of the proper operation of the LCD shutter continue.
