In this paper we describe the progress we have made in our simultaneous length
measurement and the femtosecond comb interferometric spectroscopy in a conventional …

A new contactless method based on frequency-scanning heterodyne interferometry is
proposed to measure the absolute length of opaque blocks with fragile reflective surfaces …

Extrinsic optical fiber Fabry–Perot (F–P) high temperature sensors using Al 2 O 3 ceramic
tubes were fabricated by a microscope equipped with a CCD whose scaleplate has been …

In this paper, a novel principle of contactless gauge block calibration is presented. The
principle of contactless gauge block calibration combines low-coherence interferometry and …

A novel method of gauge block measurement without wringing onto a glass platen is
proposed. By using tandem low-coherence interferometry to perform remote measurements …

This paper presents a contactless system for automatic gauge blocks calibration based on
combination of laser interferometry and low-coherence interferometry. In the presented …

Optical (eg interferometric or laser focus probe) measurement of dimensions must be
corrected to take into account phase change on reflection and the influence of surface …

The usage of computerised numerical control (CNC) machines requires accuracy
verification to ensure the high accuracy of the processed products. This paper introduces an …

This paper presents a method implemented in a system for automatic contactless calibration
of gauge blocks designed at ISI ASCR. The system combines low-coherence interferometry …

The calibration of length is related to the national economy and people's livelihood. The
traditional calibration of length value was sent the uncalibrated instrument to the laboratory …
