抄録

This paper describes a vemier-type multiturn absolute encoder which uses a spatial filter to interpolate between encoder slit positions. The absolute angle can be derived from the optical encoder which uses an LED, photodiode array and coded disc consisting of three tracks. The accuracy of angular measurement for a prototype encoder was as high as 1/100000, and the encoder can respond up to 3000 rpm. The shaft revolutions are tallied by a magnetic bubble counter which uses a "memory wheel" principle to count up to 32487 turns. No electrical energy is used to store data or count revolutions.
