Define minimum angle of resolution
WebThe Rayleigh criterion is named after English physicist John William Strutt, 3 rd Baron Rayleigh (1842-1919) who investigated the image formation of telescopes and microscopes in the late 19 th century. Rayleigh defined the resolution limit as the separation where the central maximum of the Airy pattern of one point emitter is directly ... WebOct 16, 2015 · For linear encoders, resolution designates the number of measuring units per distance (inch or millimeter), whereas for rotary encoders, it refers to the number of measuring units per revolution (also called pulses per revolution, or PPR) or per degree of angle. The resolution of an absolute encoder is often given in bits, which are binary ...
