how do digital vernier calipers work?
Digital vernier calipers work by having a digital encoder (explained later) attached to a small gear which turns on a rack gear (long, linear gear) which runs along the length of the caliper.
The digital encoder has a large number of alternating opaque and transparent bands arranged radially around a disk which is turned by the small gear. Two led/phototransistor pairs monitor the passage of the bands. By watching in pattern of light transmission, and which phototransistor sees the change first, a small digital circuit determines how many bands have passed from the zero point.
Because the gear ratios are fixed, and the bands on the disk are fixed, the circuit is programmed to translate one band into a certain distance of the caliper. This distance is converted to the appropriate inch or millimeter value, and displayed on the LCD.
