Wavelength sensitivity in blindsight [PDF]

open access: yesNature, 1989
Blindsight--the residual visual functions observed in visualfield defects resulting from destruction of part of the primary visual cortex (striate cortex) even though visual stimuli presented in the field defect are not consciously perceived--has generated new insights into the nature of consciousness and the role of the extrastriate pathways in visual

New rest wavelength determinations for 7 mid-infrared fine structure lines by ISO-SWS [PDF]

open access: yesAstrophys.J.Suppl. 136 (2001) 221, 2001
Observations of the planetary nebulae NGC6302, NGC6543 and NGC7027 by the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO) have been used to determine rest wavelengths of spectral lines. We report on improved accuracies for wavelengths of 7 mid-infrared ionic fine structure lines.

Optical detection and modulation at 2µm-2.5µm in silicon [PDF]

open access: yes, 2014
Recently the 2µm wavelength region has emerged as an exciting prospect for the next generation of telecommunications. In this paper we experimentally characterise silicon based plasma dispersion effect optical modulation and defect based photodetection ...

Effects of the long wavelength-filtered continuous spectrum on natural refractive development in juvenile guinea pigs [PDF]

open access: yesInternational Journal of Ophthalmology, 2019
AIM: To investigate the effects of spectral composition and light intensity on natural refractive development in guinea pigs. METHODS: A total of 124 pigmented guinea pigs (2-week-old) were randomly assigned to three groups at high (Hi; 4000 lx), medium

Modulation instability induced by cross-phase modulation in a dual-wavelength dispersion-managed soliton fiber ring laser [PDF]

open access: yesAppl. Phys. B, 2010, 2010
We report on the observation of modulation instability induced by cross-phase modulation in a dual-wavelength operation dispersion-managed soliton fiber ring laser with net negative cavity dispersion. The passively mode-locked operation is achieved by using nonlinear polarization rotation technique. A new type of dual-wavelength operation, where one is

Cascaded wavelength conversion by four-wave mixing in a strained semiconductor optical amplifier at 10 Gb/s [PDF]

open access: yes, 1997
We demonstrate for the first time cascaded wavelength conversion by four-wave mixing in a semiconductor optical amplifier. Bit-error-rate performance of

Light Color and the Commercial Broiler: Effect on Ocular Health and Visual Acuity

open access: yesFrontiers in Physiology, 2022
Light is a critical management factor for broiler production, and the wavelength spectrum, one of its components, can affect bird physiology, behavior and production.

Nanosecond channel-switching exact optical frequency synthesizer using an optical injection phase-locked loop (OIPLL) [PDF]

open access: yes, 2004
Experimental results are reported on an optical frequency synthesizer for use in dynamic dense wavelength-division-multiplexing networks, based on a tuneable laser in an optical injection phase-locked loop for rapid wavelength locking.

Research on infrared emission spectra of pulverized coal ash deposits [PDF]

open access: yesFME Transactions, 2013
This paper deals with thermal radiation properties of ash deposits on a pulverized coal boiler of an electric power plant. Normal emittance spectra in the 2.5-25 μm interval, and total normal emittance, were measured on 2 kinds of ash layers of a mm ...
