The situation is simpler if the column lattice is helically distorted perpendicular to the column axes blocks of parallel columns are stacked on top of each other with a finite angle between the columns of adjacent blocks (Figure 11.10) [18], The blocks are thus separated by planar tilt grain boundaries, and parallel linear screw disclinations lie within these boundary planes (Figure 11.11). This structure is perfectly analogous to the twist grain boundary phases of chiral smectic liquid crystals. 

The theory of the dielectric properties of chiral smectic liquid crystals is far from complete, particularly with respect to a molecular statistical approach. Simple Landau theory [31 ] gives expressions for the contributions of soft modes (jj g) and Goldstone modes (Xo) to the low frequency permittivity as ... 

Display devices based on nematic liquid crystals, notably small liquid crystal televisions, are used as SLMs due to their increased availability [1]. However, in most of the above applications the speed of operation is important, and nematic liquid crystals are too slow, so the emphasis here is on SLMs that use the faster electrooptic effects to be found in chiral smectic liquid crystals. We will start by looking at how these interact with light.
