"suppresses crystal's helical structure applying electric fields, allowing voltage polarity dictating molecular rotation/ optical processing behavior... reversing voltage polarity allows single component to rapidly alternate between 1st- or 2nd-order spatial edge detection/ standard bright-field imaging... 62 μ s average switching speed (nearly 3 orders of magnitude faster), stable >1.8 million switching cycles... effective on both intensity targets/ phase-only biological samples... scalable, low-latency... biomedical inspection"
