Testing of Visual Field with Virtual Reality Goggles in Manual and Visual Grasp Modes
Example of luminance and dB calibration for OLED microdisplay. (a) Measured luminance versus video control level (gray level). Average luminance obtained in a series of 6 measurements performed over a period of 8 months with error bars representing the standard deviation. Solid red line is a cubic spline fit to the measured averaged data. (b) Stimulus intensity on the Humphrey decibel scale (dB) as a function of video level. Points represent dB values corresponding to consecutive integer video levels on 8-bit scale. Solid lines represent standard deviation associated with reproducibility of luminance measurements.
