Colourmap the absolute XYA scale

ColourmapTM dot scale technology is a patented, absolute XY and angle scale system. A matrix of coloured dots is used to encode both X and Y positions. At any position on the scale the pattern of coloured dots will be unique, allowing X and Y positions and the angle of the sensor to be calculated. Because the angle of the sensor is also measured, there is no need to constrain the moving element orthogonally. This means that the system could potentially revolutionise current thinking with regard to applications that require two-dimensional measurements.
