Research ArticleOpen accessLength Measurement of Long Gauge Blocks by InterferometerKanokporn Kohmun, Pichet Limsuwan, Monludee Ranusawud, Prathan BuranasiriA 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 … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 26 Sep 2020 · 7,099 accessesView PDF Cite

Research ArticleOpen accessEffect of the Papaya Latex on the Visibility of FingerprintChantira Boonsri, Pichet Limsuwan, Prathan BuranasiriThe effect of the papaya latex on the visibility of fingerprint was investigated. The fingerprints of the thumb without and with touching papaya latex for 5 and 10 min were prepared on the glass slides and captured by CMOS camera. The fingerprint images were reconstructed and the transverse intensity profiles were performed. The valley depth and the ridge width for … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 27 Jul 2020 · 7,224 accessesView PDF Cite

Research ArticleOpen accessDetermination of Dynamic Viscosity of Viscous Oils using Mach Zehnder Digital Holographic MethodRittirong Nuansri, Pichet Limsuwan, Prathan BuranasiriThe digital in-line holography based on Mach Zehnder interferometer (MZDIH) was setup for the determination of dynamic viscosity of the viscous oils. The spherical irons were used as the falling objects in the viscous oils. The hologram images of the iron falling along its entire path were recoded as a video file on the CMOS camera. The recorded hologram images … …American Journal of Applied Sciences, Vol. 15, Issue 6 · 28 Jul 2018 · 7,687 accessesView PDF Cite

Research ArticleOpen accessComparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode Laser-Pumped Nd:YAG Laser at 532 nmPrayut Potirak, Monludee Ranusawud, Pichet Limsuwan, Prathan BuranasiriAn iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 26 May 2018 · 7,886 accessesView PDF Cite
