Dynamically Switchable 1st/2nd-Order Optical Spatial Differentiation (IMAGE)
Caption
Figure 3 | Dynamically switchable 1st/2nd-order optical spatial differentiation. a, For intensity objects. The bright-field images under -5 V and the 1st-order edge images under +5 V at 630 nm, 550 nm, 490 nm, respectively. b, For phase objects. The bright-field images under -5 V and the 2nd-order edge images under +5 V at 600 nm. c, Response time of bright-field imaging to differentiation and differentiation to bright-field imaging, respectively. d, Analysis of switching cycles at 10 Vpp and 1 kHz after operating 0 cycles, 0.9 million cycles and 1.8 million cycles. e, The polarized optical micrograph (middle region of the sample, at -5 V) and analysis of switching cycles at 10 Vpp and 1 kHz after 200 days. The white and yellow double-ended arrows label the direction of the polarizer and analyzer, respectively. The scale bar is 100 μm.
