“…This can also be used along with other third party software, making it more attractive for development applications such as this one. Apart from these, the other reason for choosing LabVIEW is for its inbuilt server facility that can be utilized to publish a GUI for Internet access to the experiments [13], [14].…”

Use of Internet technology for offering physical laboratory courses are a relatively new challenge for engineering educators. Towards this the paper presents the design and development of an Internet based facility that will be used to offer an undergraduate laboratory course. The facility will enable students to perform experiments involving real-life hardware over the Internet. The system is developed by using commercially available hardware and software technologies. The highlighting features of the developed system are its cost effectiveness, modularity in design, web security, and system and student evaluation facility. The system has the provision to monitor the extent of utilization of the facility to assess its usefulness. Multiple experiments can be delivered through the systems at any time; however, one experiment can be performed by a single student, while others can view the results.Index Terms-Computer interfacing, distance learning, Internet-based laboratory, and wed development.

“…A structure for sending particular command to analyzer is shown in this figure, and it represents one of the three stages, needed for full data interchange between computer and measurement hardware. Such program structure is universal and it can be used to implement most of GPIB functions [2]. Depending on what operation has to be performed, appropriate command (or command sequence) is entered into "Transferred string" field.…”

“…Most programs use just 6 to 8 commands so it is not necessary to learn all of the GPIB commands to develop a good GPIB program. Program complexity increases as the number of devices being controlled and number of tests increase [2,6].…”

Development of optical technologiesrapidly stimulates analysis of more complex signals. Spectrum measurement demands the use of sophisticated combination of hardware and software for optical instruments. The purpose of this work is to create a computer program for manipulation of optical spectrum analyzer HP 71451A. It is also necessary to select suitable system operation algorithm. System control design should span: algorithm of operation, amount of possible functions, indication type and user interface. This investigation implements the creation of such automated measurement system using two different programming approachesgraphic programming using LabVIEW and textbased programming using LabWindows.

“…The FFT algorithm exploits symmetries in the mathematics of the calculation to exponentially reduce the computational complexity required. For a data-set of 10 6 points, the FFT is 50,000 times faster than the discrete Fourier transform [10]. The horizontal scaling in the frequency domain is limited to Fs/2 because of the Nyquist-Shannon Sampling Theorem.…”

Point-Spread Function Assessment of SG-DBR Based Swept Source for OCT Imaging

Swept Source Optical Coherence Tomography (SS-OCT) is a medical imaging technique that requires high repetition rate, widely-tunable coherent laser sources. Sampled grating distributed Bragg reflector (SG-DBR) lasers are proven in telecom applications and are expected to fulfill the requirements for SS-OCT at a significantly lower cost than alternative solutions. Constructed entirely on a semiconductor substrate, SG-DBR lasers require four synchronized waveforms to modulate the output wavelength and intensity. Because of this unique tuning mechanism, there are a number of systematic and noise sources that can affect the quality of the OCT point-spread function (PSF). Based on these noise sources, software is developed to simulate the waveforms in an SS-OCT system and determine the factors that limit width of the PSF central peak and the broadband skirts. Design curves are then created to specify the requirements to obtain a given performance. Next, experimental tests are performed on a JDS Uniphase C-band SG-DBR laser to assess its performance limitations. Finally, by comparing theory and experiment, recommendations are made on acceptable systematic and random noise errors induced in the PSF. v Table of Contents List of Figures vi Chapter 1: Introduction Chapter 2: SG-DBR Laser Background and Technical Introduction
