Simple method of characterizing the spatial luminance distribution at the user position for autostereoscopic 3-D display

The image quality of autostereoscopic 3-D displays strongly depends on the user position. So, characterization of the spatial luminance distribution at the user position is important. For the measurement of the spatial luminance distribution, a method that places a diffuser screen at the user position and is illuminated by a 3-D display has been investigated. By placing the diffuser screen and 3-D display non-parallel, the luminance distribution at the various distances can be determined. Though the accuracy of this measurement method is somewhat limited, the measuring procedure is fast and simple, compared with other time-consuming methods.
