The Geometrical Optics Lab is a software add-on for LabVIEW. The add-on includes over 15 visualized experiments that help students learn the basics of geometrical optics and fiber communication based on the NI ELVIS Electronics Device. Go to download page and download labVIEW Run Time engine and install it. 1) Select the run button to run the experiment. 2) Go the toggle switches which are located on both the analog and digital transmission system and change. LabVIEW is an application development program that was developed by National Instruments in 1986 to integrate science and engineering tasks by interfacing computers with instruments for collecting, storing, analyzing, and transmitting data while, at the same time, providing an effective user. ics and Communication Engineering of the College of Engineering, Trivandrum.

The Geometrical Optics Lab provides a physics educational laboratory based on the NI Engineering Laboratory Virtual Instrumentation Suite (NI ELVIS). In this paper, a Labview-based system is proposed for fiber-optic faults detection. The wavelet threshold denoising method combined with Empirical Mode. This paper presents the development and application of LabVIEW for automating measurements related to optical amplifiers, facilitating remote testing of fiber-optic systems, and managing fiber sensor technologies.
