Time-multiplexing: n-ary codes (I)

Using a 4-ary code, 3 patterns are used to encode 64 stripes (Horn & Kiryati)

•n-ary codes reduce the number of patterns by increasing the number of projected intensities (grey levels/colours) à increases the basis of the code

•

•The number of patterns, the number of grey levels or colours and the number of encoded stripes are strongly related à fixing two of these parameters the reamaining one is obtained

Using a binary code, 6 patterns are necessary to encode 64 stripes
