ABSTRACT
The color of material can be determined by using the optical system which measures the intensity of reflected light and its incident beam, and based on CIE standard developed by Newton the Quantitative identification can be found.
To carry out this measurement, an optical system was constructed using a...

ABSTRAK
Erbium doped fiber amplifier (EDFA) menjadi kunci utama komponen
dense wavelength division multiplexing (DWDM) dalam sistem komunikasi fiber optik.
EDFA L band relatif bekerja pada inversi populasi rendah dimana energi
absorpsi dan emisi bekerja pada level energi konvensional dengan menghasilkan penguatan positip. Pola daya laser diode pumping (LDP) menjadi bagian terpenting dalam pengaturan...

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...

ABSTRAK
Photodioda dapat digunakan dalam sistem komunikasi optik, tetapi aplikasi yang
utama digunakan sebagai link untuk gelombang mikro dinamik. Implementasi
dalam sistem gelombang mikro, photodioda akan ditempatkan dalam sebuah
modul yang dikenal dengan modul microwave packaging. Proses packaging ini
memuat waveguide photodioda dan konektor microwave yang diintegrasikan
bertujuan untuk memperoleh penjumlahan sinyal gelombang mikro di bagian
outputnya....

Ucuk Darusalam, author
Atmospheric turbulence is the major problem in FSO communications where beam wander and spatial noise modulation into optical propagation can cause severe problems result in performance degradation. Beam wander and spatial noise leads to fluctuations in signal intensity and maximum reception of noise on photodetector.
Generally, spatial-diversity, time-diversity, cooperative diversity, photo...

Substitusi Mg pada site-La material LaFeO3 (La1-xMgxFeO3, dengan x=0.0, 0.1, 0.2 dan 0.3) telah dilakukan dengan metode sintesis sol-gel. Sifat struktur material perovskite La1-xMgxFeO3 dikarakterisasi menggunakan XRD, XRF, BET, SEM dan EDX. Analisis XRD material La1-xMgxFeO3 menunjukkan struktur Orthorhombic dengan space group Pnma. Terjadi penurunan crystallite size seiring...
