METHOD AND DEVICE FOR CONVERSION OF MOVEMENTS OF AN OBJECT INTO CODE

摘要

The substance of the invention consists in separate coding of the movement values of an object according to higher and lower code orders, the higher orders being coded in cyclic code by division of the range of the movement values into n parts which are each coded through their own scale multiplier. The code of the lower orders is shifted in relation to the code of the higher orders and the movement code is reproduced by forming, by means of reading elements (2, 3) of electric signals corresponding to the lower and the higher code orders. The electric signals corresponding to the lower orders are converted by means of a forming unit (4) into four electric signals which are equal in amplitude and are mutually 90 DEG out of phase. The electric signals corresponding to the lower orders are interpolated and the numerical code of the lower orders is formed by means of a comparator unit (6) and a logic processor (7). The cyclic code of the higher orders is converted into binary code by means of a comparator unit (8), a converter (9) and a logic processor (10). The shifted codes of the lower and higher orders are converted into binary code by means of a converter (11).
