Optoelectronics Letters - Tập 17 Số 7 - Trang 427-431 - 2021
Research on optical fiber magnetic field sensors based on multi-mode fiber and spherical structure
Optoelectronics Letters - - 2017
A magnetic field sensor with a magnetic fluid (MF)-coated intermodal interferometer is proposed and experimentally demonstrated. The interferometer is formed by sandwiching a segment of single mode fiber (SMF) between a segment of multi-mode fiber (MMF) and a spherical structure. It can be considered as a cascade of the traditional SMF-MMF-SMF structure and MMF-SMF-sphere structure. The transmissi......
Optical fiber sensor by cascading long period fiber grating with FBG for double parameters measurement
Optoelectronics Letters - Tập 13 - Trang 372-375 - 2017
An optical fiber sensor for strain and temperature measurement based on long period fiber grating (LPFG) cascaded with fiber Bragg grating (FBG) structure has been proposed and realized both theoretically and experimentally. Theoretical analysis shows that two microstructures with similar sensitivities cannot be used for double parameters measurement. The LPFG is micromachined by the CO2 laser, an......

Organic light emitting devices employing non-doped structure
Optoelectronics Letters - Tập 13 - Trang 192-196 - 2017
A kind of efficient non-doped white organic light-emitting diodes (WOLEDs) were realized by using a bright blue-emitting layer of 4,4-bis(2,2-diphenylvinyl)-1,1-biphenyl (DPVBi) combining with red emitting ultrathin layer of [2-methyl-6-[2-(2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizin-9-yl)ethenyl]-4H-pyran-4-ylidene]propane-dinitrile (DCM2) and green emitting ultrathin layer of 10-(2-benzothiazol......
Study of the imaging property of a fluorescent confocal microscopy with a phase-only filter in an extended source
Optoelectronics Letters - Tập 3 - Trang 299-302 - 2007
The phase information of an enlarged source is reconstructed with an annular two-zone phase-only filter in a fluorescent confocal scanning optical microscope for resolution improvement. The dependences of its resolution on the source size and on the phase transmission of the outer annular zone of the filter are investigated theoretically by use of its three-dimensional optical transfer function (3......

Measurement of air pollutants by differential optical absorption spectroscopy using a Cassegrain telescope with fibers
Optoelectronics Letters - Tập 9 - Trang 313-316 - 2013
A differential optical absorption spectroscopy (DOAS) method is presented and used for the air pollutant detection. The novel measurement frame employs a Cassegrain telescope and a combined fiber bundle. The emitting and receiving fibers are bundled together at one port. The common port is placed at the focus of the Cassegrain telescope. The total length of the prototype is reduced to about 1/2 of......
