METHOD FOR READING VALUE Russian patent published in 2000 - IPC

FIELD: direct and inferential measurements. SUBSTANCE: method involves looking onto scale of measuring instrument, which gives rough value, relative movement of measuring instrument, which has scale, or its elements with optical force greater than zero, and head of operator, reading parallax and/or another scale shift (for example, aberration) and/or relative parallax relative shift and/or another relative shift (for example, aberration) or various real and/or imaginary images of at least one scale. This provides correction for rough value or directly precise value. EFFECT: increased precision of reading, simplified reading operation, confidentiality of reading without mechanical contact between instrument and object, simplified actions of operator, simplified design and decreased weight and size of instruments, increased functional capabilities. 3 dwg
