Abstract
It is shown that a liquid crystal material such as MBBA may be encapsulated in a wedge type cell to form a liquid crystal wedge. Such a wedge can split an incident laser beam into two orthogonally polarized beams and hence can find applications where such splitting is required. It is also shown that such a wedge can also be used as a lateral shearing interferometer. Two simple methods are indicated to distinguish between well-crystallized regions and badly crystallized regions.
