Method for narrowing the bandwidth of an optical signal |
| abstract |
A method for narrowing the bandwidth of an optical signal comprising directing a linearly polarized optical signal through an optically negative liquid crystal film and a linear analyzer arranged in tandem is disclosed. The optically negative liquid crystal film is chosen to have characteristics such that some of the light is extinguished whereas the remainder escapes extinction and is transmitted. |
