摘要：
We present a simple technique for real time liquid crystal panel intensity transmission calibration. The experimental method is based on studying a test image displayed on the modulator. Using those images, we can display different calibration curves. The visualization of the intensity transmission curves in real time allows to adjust the correct control parameters (brightness, contrast, gamma, etc.) that gives a linear response of the intensity transmission with the graylevels.
