Construction of laser raman system using diode laser and Its performance
(© 2009 Journal of Bangladesh Academy of Sciences, 2009)
We constructed a laser Raman system using a commercially available infrared diode laser. The diode laser is used without any temperature controller in a stabilized power supply. Good quality Raman spectra of sufficient ...
Calculation of the bandwidth of a graded-index optical fiber using experimentally measured quantities
(© 2007 Dhaka University Journal of Science, 2007-01)
Computer simulation of Fresnel diffraction from rectangular apertures and obstacles using the Fresnel integrals approach
(© 2005 Elsevier Ltd., 2007-03)
In this paper, we describe a new computer simulation technique of generating Fresnel diffraction images from rectangular apertures of arbitrary dimensions by using Fresnel integrals instead of the more common fast Fourier ...
Electronic speckle pattern interferometry and related techniques using digital still cameras

Construction and operation of a dispersive laser raman spectrograph using interference filter
(© 2008 Journal of Bangladesh Academy of Sciences, 2008)
A dispersive laser Raman system was designed and constructed using a helium-neon (He-Ne) laser as an excitation source, and an interference filter in the reflection mode for Raleigh filtering instead of the more common ...
Determination of ratio of unsaturated to total fatty acids in edible oils by laser Raman spectroscopy
(© 2009 Asian Network for Scientific Information, 2009)
In this study, a homemade laser Raman spectrometer was used to examine the Raman spectra of different edible oils, such as canola, corn, soybean, sunflower, palm and coconut oils. To avoid severe fluorescence effects which ...
Elemental profiling of surface water around Dhaka city by laser induced breakdown spectroscopy
(© 2009 Journal of Bangladesh Academy of Sciences, 2009)
Using the technique of Laser Induced Breakdown Spectroscopy (LIBS), which uses a pulsed laser to create plasma and advanced spectroscopic techniques, we analyzed the contents of surface water (river water) around the city ...
