Displacement and vibration measurement with the Moiré technique
By superposing two Ronchi gratings with close pitches, a new periodic pattern, i.e., the so-called Moiré fringes, is generated with much greater pitch. The advantage of the Moiré fringes is its magnification compared to the constructing gratings pitch. Furthermore, it has a great sensitivity to movement and rotation of the primary gratings which leads to precise measurements.
Fanavari Kahroba Company started its activities in 2011 with manufacturing EMC Camera device and began to be a member of science and technology park of University of Tehran since 2012. Later on with devising thin film thickness measurement device and far distance Moiré measurement device, its official activities in precis measurement industry begun. Its optical surface topography measurement devices was introduced in 2014. Thanks to first ranked graduate elites, Kahroba’s company has devised several products with no international competitors. In addition, its products have the advantage of consumers support, precision calibration and being financially affordable for local manifactures. Among the highest valued policies of Kahroba’s company, science management can be mentions. Its most precious investment is expert graduate researchers. Reaching high shares of optical based measurement devices in the international market is one of the perspectives of Kahroba’s company. This aim not only does increase national economical growth, investment return and export, but also it does help to improve scientific foundation of the country and creating more job opportunities. In order to achieve this goal, Kahroba’s mission is devising high precise optical based measurement devices without international competitors based on national scientific experts.
