Spectral line extraction based on ant-colony algorithm
EURASIP Journal on Advances in Signal Processing, 2021 A spectral-line-extraction algorithm based on the ant-colony algorithm is proposed to address the difficulty of extracting spectral lines in low signal-to-noise ratio conditions, and the problem that results from the optimal path algorithm falls into ...

“Structure of Spectral Lines” [PDF]
Nature, 1947 In Nature of August 23, p. 244, Dr. D. A. Jackson reviews my recent book on “High-Resolution Spectroscopy” (Methuen, 1947). After considerable hesitation and with much reluctance, I feel compelled to comment on several misrepresentations made by Dr. Jackson.

Subnanosecond spectral diffusion measurement using photon correlation [PDF]
, 2010 Spectral diffusion is a result of random spectral jumps of a narrow line as a result of a fluctuating environment. It is an important issue in spectroscopy, because the observed spectral broadening prevents access to the intrinsic line properties ...
