A high-sensitivity OH 5-cm line survey in late-type stars
, 2002 We have undertaken a comprehensive search for 5-cm excited OH maser emission from evolved stars representative of various stages of late stellar evolution. Observed sources were selected from known 18-cm OH sources. This survey was conducted with the 100-

Detection of radio frequency magnetic fields using nonlinear magneto-optical rotation [PDF]
, 2006 We describe a room-temperature alkali-metal atomic magnetometer for detection of small, high frequency magnetic fields. The magnetometer operates by detecting optical rotation due to the precession of an aligned ground state in the presence of a small ...

Review of Detection Limits for Various Techniques for Bacterial Detection in Food Samples
NanomaterialsFoodborne illnesses can be infectious and dangerous, and most of them are caused by bacteria. Some common food-related bacteria species exist widely in nature and pose a serious threat to both humans and animals; they can cause poisoning, diseases ...

Detection limits of confocal surface plasmon microscopy
Biomedical Optics Express, 2014 This paper applies rigorous diffraction theory to evaluate the minimum mass sensitivity of a confocal optical microscope designed to excite and detect surface plasmons operating on a planar metallic substrate. The diffraction model is compared with an intuitive ray picture which gives remarkably similar predictions.

General limit to non-destructive optical detection of atoms
, 2004 We demonstrate that there is a fundamental limit to the sensitivity of phase-based detection of atoms with light for a given maximum level of allowable spontaneous emission. This is a generalisation of previous results for two-level and three-level atoms.

Approaching the Heisenberg limit with two mode squeezed states [PDF]
, 2002 Two mode squeezed states can be used to achieve Heisenberg limit scaling in interferometry: a phase shift of $\delta \phi \approx 2.76 / $ can be resolved.

On a generalization of the binomial distribution and its Poisson-like limit
, 2011 We examine a generalization of the binomial distribution associated with a strictly increasing sequence of numbers and we prove its Poisson-like limit. Such generalizations might be found in quantum optics with imperfect detection. We discuss under which
