Abstract: | We present a simple technique for the determination of pixel size and pitch of liquid crystal (LC) based spatial light modulator
(SLM). The proposed method is based on optical diffraction from pixelated LC panel that has been modeled as a two-dimensional
array of rectangular apertures. A novel yet simple, two-plane measurement technique is implemented to circumvent the difficulty
in absolute distance measurement. Experimental results are presented for electrically addressed twisted nematic LC-SLM removed
from the display projector. |
