imaging with a 90frames s microboloMeter focal plane array and high Power terahertz free electron laser
Applied Physics Letters, 2008Co-Authors: M A Demyanenko, D G Esaev, B A Knyazev, G N Kulipanov, N A VinokurovAbstract:An uncooled microboloMeter focal plane array (FPA) has been developed and used for imaging of objects illuminated by monochromatic coherent radiation of a free electron laser tunable in the range of 1.25–2.5THz. A sensitivity threshold of 1.3×10−3W∕cm2 was obtained for the FPA with a homemade absolute interferometric Power Meter. Videos up to 90frames∕s were recorded in both transmission and reflection/scattering modes. When objects were illuminated by laser radiation scattered by a rough metal surface, speckled images were observed. Good quality terahertz images were achieved through the fast rotation of the scatterer.

Analisis Sensor Pengukuran Konsentrasi Glukosa Prinsip Macrobending Pada Serat Optik Multimode Step-Index
2018Co-Authors: Hafida, Nura HajarAbstract:Telah dikembangkan sensor konsentrasi glukosa dengan prinsip macrobending dari serat optik multimode step-index dengan variasi panjang kupasan 2 cm, 3 cm, dan 4 cm. Setiap panjang kupasan dilengkungkan dengan diaMeter kelengkungan 2 cm, 3 cm, dan 4 cm. Larutan glukosa yang diuji memiliki konsentrasi 0% (aquades), 5%, 10%, 15% dan 25%. Sumber cahaya yang digunakan LED dengan panjang gelombang 660 nm dan detektor yang digunakan yaitu BF5R-D1-N yang telah dikalibrasi dengan menggunakan Optical Power Meter. Dari hasil pengukuran diperoleh bahwa semakin besar diaMeter kelengkungan serat optik semakin besar pula daya keluaran, dan semakin panjang daerah kupasan semakin kecil daya keluaran. ================ A Glucose concentration sensor has been developed with macrobending principle on multimode step-index optical fiber with variation of peel length 2 cm, 3 cm, and 4 cm. Each peel long curved with curvature diaMeter of 2cm, 3 cm, dan 4 cm. The tested glucose solution had a concentration of 0% (aquades), 5%, 10%, 15% and 25%. A BF5R-D1-N is used as light source and detector which has been calibrated by using Optical Power Meter. The results of experiment show that correlation between optical Power output with curvature diaMeter, and also peeling area of optical fiber
