“…To meet such requirements the interferometric system should be placed in a special chamber with many parameter measuring sensors to maintain an effective thermal and pressure isolation. These sensors as well as temperature fluctuation can bring in the uncertainty in such precise length measurements [3]. Another important uncertainty source in dimensional metrology is the abbe error which occurs due to the difference between the axis of the measurement object and the axis of the measuring device.…”

To perform the calibration of total stations under laboratory conditions, lack of space is a common issue. The paper presents the analysis of applied solutions for short distance measurements and assumptions of the construction development of a linear test bench for cyclic error determination. Various aspects of improvement are explained in the paper, and the preliminary design of a linear test bench being developed at Vilnius Gediminas Technical University is presented.

“…The gauge block interferometer systems were developed by various National Metrology Institute (NMI) to measure the length of gauge blocks (Hamid et al, 2005;Darnedde 1992;Lewis 1994;Decker and Pekelsky, 1997). In addition, the interferometers for the length measurement of long gauge blocks up to 1000 mm were developed by various researchers Haitjema and Kotteb (1998) developed an interferometer for the calibration of long gauge blocks in the 100-1,000 mm range.…”

A gauge block interferometer with a vacuum chamber was designed and constructed for the measurement of gauge block lengths between 10 to 1,000 mm. In the chamber, four gauge blocks under the length measurement can be mounted on the measuring table. Furthermore, the length of all four gauge blocks can be measured continuously in one measurement. In this study, four gauge blocks with the nominal length of 125, 200, 400 and 500 mm were used for the length measurement. The environment parameters in the vacuum chamber including temperature, pressure, relative humidity and CO2 concentration were measured. The refractive index of air which depends on environment parameters was determined by using updated Edlén equation. Then, the lengths of four gauge blocks were measured and found to be 125.00025, 200.00019, 400.00070 and 500.00064, respectively.

“…Interferometry is one of such methods that are primary experimental techniques to measure the plasma refractive properties [4]. Different interferometry techniques were described to measure gas temperatures in different systems [5][6][7][8][9][10]. Tomita et al measured the temperature of unburned gas before knocking in a spark-ignition engine using Mach-Zehnder laser interferometry [3].…”
