  • Evolving toward digital
    Bore gages are digital, whether it’s an air gage or a three-point-contact gage. There are still a few old-timers who trot out ID micrometers once in awhile, but most measurement devices are digital for speed and accuracy.
  • Three-dimensional measurement system with microtactile sensor
    measurements using a Id precision linear transducer is 9 nm (3) in a bandwidth of 1 Hz. First twodimensional measurements on small ring gauges (cylindrical boreholes) were recently carried out [9] using a 2D air bearing positioning device which exhibits a high vibrational noise level.

  • Microinterferometer Transducer
    An air - bearing microinterferometer transducer is being developed to provide for increased accuracy, range, and linearity over conventional linear variable differential transformer (LVDT) transducers. The conventional LVDT's are used on multiple -probe sweep gauges to measure deviation from true surfaces to revolution. These LVDT transducers are null devices , and their high accuracy deteriorates rapidly as they move from zero... Miniature glassware has been obtained and a microinterferometer constructed inside an 0.315- inch - ID transducer.
