Differential interference contrast (DIC) observation is powerful tool for the week phase sample such as a biological cell. Then, DIC prism which is an important element is usually extremely expensive and the shearing distance is fixed. If we use a LC cell as a DIC prism, electronic tunable DIC system can be attained. In this work, we investigated the lateral shearing property of TN LC cells aiming to utilize it as the DIC prism.
