ABSTRACT
A non-mechanical method of measuring temporally coherent light, which may be dominated by incoherent background radiation, has been developed. The measurement method is based on the modulated signal produced by the temporally coherent radiation through a LiTaO3 crystal.
In the study, the coherent and incoherent lights are combined. To detect...

ABSTRACT
The molecular weight of Polymer material can be determined using optical system by measuring the intensity of scattered light at low angle light scattering and its the incident beam, based on Rayleigh scattering have developed by Debye has known as Static Light Scattering.
To carry out this measurement, an...

ABSTRACT
An experimental micro optical branching circuit (HCBC) array has been constructed by the use of planar microlens. Three substrates of 3x1 nicrolens array have been used as collimating and focusing elements in the proposed circuit. A cube beam splitter was utilized as branching element with a branching ratio 1:1, for...

Segmentasi dan ekstraksi ciri dari citra USG merupakan salah satu pekerjaan yang cukup sulit, karena batas tepi antara obyek dan background tidak begitu jelas. Ketidakjelasan tersebut disebabkan oleh beberapa hal diantaranya adalah adanya derau (noise) yang disebabkan oleh hamburan karena ketidak homogenan dari media yang dilalui oleh gelombang ultrasonik, serta...

ABSTRACT
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...
