Comparing the liquid crystal technique with such electrochemical methods (also requiring no cumbersome or expensive facilities) as electrographic, bubble, and the so-called copper-gelatine methods, we should mention the better resolution of the former [86]. As a rule the resolution of the conven-... 

The maximum possible resolution of the liquid crystal technique obtained for pores in an Si02 layer, about 100 nm thick, was 0.01 fim at 7 60 V [84, 86]. Such a high sensitivity of the method is due to the fact that the area of deformation in a liquid crystal layer considerably exceeds the defect in size. In other words, the layer acts as a magnifying lens.
