Optical Interference Coatings Conference (OIC) 2019, 2019
Narrowband pass filters are generally poor as narrowband angle filters. A tilted narrowband pass filter, however, is an improved narrowband angle filter, but only for rays in one plane of incidence. It is shown that a combination of two tilted narrowband pass filters will select light from all narrow angle patches in an incident cone.

Narrowband Magnetic Particle Imaging
IEEE Transactions on Medical Imaging, 2009The magnetic particle imaging (MPI) method directly images the magnetization of super-paramagnetic iron oxide (SPIO) nanoparticles, which are contrast agents commonly used in magnetic resonance imaging (MRI). MPI, as originally envisioned, requires a high-bandwidth receiver coil and preamplifier, which are difficult to optimally noise match. This paper

Narrowband chemical-shift imaging
Applied Optics, 1985In this paper we introduce an efficient method for NMR chemical shift imaging which is especially well suited for imaging proton chemical shifts. With realistic observation times and pulse sequences, one is operating close to the theoretical limits of this method.

Ocean 72 - IEEE International Conference on Engineering in the Ocean Environment, 1972
A narrowband HF-SSB system designed to meet the requirements recommended by the Joint WMO/IOC group of experts on telecommunications for oceanographic data and command telemetry transmissions is described. The building blocks that compose this ocean data buoy HF telemetry system, and their more important characteristics, are listed.

Journal of the Canadian Association of Radiologists, 1983
A narrowband communication system using the Canadian satellite ANIK-B was used to transmit radiographic images from northern Quebec to Montreal. This slow scan television (SSTV) system was used to study the accuracy of the radiologist's interpretation, both with samples of pre-selected films and current patients.

SEG Technical Program Expanded Abstracts 2011, 2011
• The interfaces between the rocks above and below these layers created high acoustic impedance boundaries that reflect a good percentage of the down-going and/or up-going seismic energy. • The layers can be highly absorptive, attenuating high and mid frequencies and only passing low frequencies. • In salt provinces, as well as absorbing seismic energy,

Narrowband Ultraviolet Vapor Filter
Applied Optics, 1975A narrowband optical vapor filter based on the principle of selective specular reflection from vapors is described. The device consists of a mercury vapor cell with Brewster angle windows that selectively reflects the 2537-A line and transmits other radiation.

Narrowband electrooptic tunable notch filter
Applied Optics, 1986We describe the theory of a narrowband electrooptic tunable filter based on a Fabry-Perot etalon with distributed Bragg reflectors. The filter can be in either bulk or waveguide form. The input to the filter must be prefiltered to the stop-band of the Bragg mirrors. Once this is accomplished, the etalon possesses a very narrow notch in the Bragg filter

Narrowband auscultatory blood pressure measurement
IEEE Transactions on Biomedical Engineering, 2002Auscultatory blood pressure measurement uses the presence and absence of acoustic pulses generated by an artery (i.e., Korotkoff sound), detected with a stethoscope or a sensitive microphone, to noninvasively estimate systolic and diastolic pressures.
