" ABSTRAK
In the optical communication system, we usually use some optical components consisting oF very small lenses ior coupling, branching, and transmitting lightwaves. Optical Fiber communication system has reached an integrated optical circuitry by utilizing optical elements with distributed-index medium. On the other hand, a concept of stacked planar optics has been developed based on the characteristics of distributed index medium in planar optical elements. A group of optical components which is known as microoptics is now a further development for realizing suitable microlenses for the purpose ... "

" Pengenalan bermacam gas aroma dapat dilakukan dengan menganalisa pola keluaran dari bermacam sensor gas aroma. Makalah ini membahas pembuatan sistim pengenal jenis gas aroma dan Jaringan Syaraf Tiruan sebagai pengenal pola aroma, berdasarkan proses adsorbsi-deadsorbsi molekul gas. Sistim ini menggunakan empat buah sensor resonator kwarsa dengan frekuensi dasar 10 Mhz, masing-masing dilapis dengan membran sensitif yang mempunyai karakteristik berbeda. Adsorbsi molekul gas aroma dalam membran sensitif akan menurunkan frekuensi dasar sensor, dan ini berkaitan langsung ... "

" In spite of abundant experimental evidences supporting the viability of the laser induced shock wave plasma model for the explanation of the important features ofthe plasma and the associated spectroscopic characteristics, a controversy on the atomic excitation mechanism in the plasma has remained to be completely resolved. In this study the contributions of the shock wave model and two other most popular models, the electron-ion recombination model and thc electron collision model were thoroughly investigated. ... "

" ABSTRACT
An comprehensiove study has been carried out for the study and extension of lases induce shock wave plasma spectroscopy (LISPS) application to non metalic soft and hard samples. For this purpose, a series of experiments were conducted to investigate the dynamical process taking place in the laser plasma generated by a high power and short pulse laser irradiations on a non metal soft and hard samples it was found that in the case of non ...

" ABSTRACT
A comprehensive study has been made on the dynamical process taking place in the laser-plasma generation i.nduced by a TEA CO2 laser bombardment on metal target and non-metal target Eom low to high pressures surrounding gas. ln the case of metal target, pure zinc plate was used as a target and bombarded with 400 ml laser pulse energy. Dynamical characterization of plasma expansion and excitation were examined in detail both for target atomic emission (Zn ... "
