I'd also suspect this, having worked at a company that manufactured optical
encoders, most of these things are sinusoidal. That is far from a bad thing
though. If you build two of these and get them 90 degrees apart so you are
seeing both a sine and a cosine then you can easily sense direction and
interpolate to a high degree of accuracy. Both are major improvements : )
