The optical rotator

Journal of Microscopy, 1997
The optical rotator is an unbiased, local stereological principle for estimation of cell volume and cell surface area in thick, transparent slabs. The underlying principle was first described in 1993 by Kiêu &38; Jensen ( J. Microsc170, 45–51) who also derived an estimator of length.

Carcinogenic optical rotation

Medical Hypotheses, 1990
It is suggested that viral nucleic acid inserts in vulnerable regions of host cell DNA contribute to cell transformation by introducing 43 degrees of optical rotation at 425 nm, and that a carcinogenic event caused by DNA inserts and adducts is spurious electron ejection from important adenine molecules that may be far from insert/adduct sites.

Rotating optical fields

Journal of Modern Optics, 1998
Transversally sharply structured optical fields are discussed, which rotate upon propagation without any lateral expansion of the intensity profile. Finite-aperture approximations of such fields, realizable with phase-only and complex-amplitude recording, are demonstrated.

Recoil-Induced Optical Faraday Rotation

Physical Review A, 1995
The effects arising from atomic recoil during stimulated emission or absorption can play a dominant role in the pumpiaprobe spectroscopy of a subiaDopplers or subiarecoil2 cooled gas. The atomic recoil that accompanies spontaneous emission (SpRE) can also lead to new physical effects. One such effect, recoil induced optical Faraday rotation (RIOFR), is

Rotating optical microcavities

2007 Conference on Lasers and Electro-Optics - Pacific Rim, 2007
The Sagnac effect in rotating microcavities is studied theoretically and numerically. The frequency shift due to the Sagnac effect occurs as a threshold-like phenomenon for the angular velocity in a rotating microcavity. Above the threshold, the eigenfunctions of a rotating microcavity become rotating waves while they are standing waves below the ...
