Photoacoustic measurement in an imaging system is a unique method as it uses optical disturbance but observes its effect acoustically. Acoustical observation increases the quality of a measurement by reducing the scattering effect that often occurs in optical research. However, a few problems, such as cost and complexity, hinder development...

A study on the design and construction of measurement system of electric current of power line has been carried out. The electromagnetic induction on inductor placed near a power line was used as modulator signal of laser diode. The modulator signal in frequency signal form is obtained by converting the...

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...

[Pada umumnya sensor Fiber Bragg Grating (FBG) bekerja berdasarkan pengamatan karakteristik respon spektral FBG terhadap besaran yang ingin dideteksi. Pada tesis ini dipelajari kemungkinan pemanfaatan respon intensitas FBG untuk mengamati besaran yang ingin dideteksi, khususnya regangan statis dan dinamis. Hasil pengujian menunjukkan bahwa intensitas transmisi dan refleksi FBG berbanding lurus...
