PURPOSE To report a series of three cases of neurofibromatosis type 1 examined by near-infrared fundus autofluorescence (NIR-AF) with a scanning laser ophthalmoscope and spectral-domain optical coherence tomography (OCT) to show the characteristics of choroidal abnormalities. METHODS Retrospective case series. Six eyes of three patients were examined by conventional fundus examinations, near-...

Solar conversion to fuels or to electricity in semiconductors using far red-to-near infrared (NIR) light, which accounts for about 40% of solar energy, is highly significant. One main challenge is the development of novel strategies for activity promotion and new basic mechanisms for NIR response. Mother Nature has evolved to smartly capture far red-to-NIR light via their intelligent systems du...

abstract the assessment of ripeness is a major part of quality evaluation and depends on several factors such as soluble solid content (ssc), acidity and firmness. most of the methods that measure these qualities are destructive. so it is essential to develop an efficient and nondestructive method for measuring internal attributes of fruit. the objective of this study was to investigate visible...

BACKGROUND Near-infrared light (NIR, 0.8-1.5 microm light) has been used in therapeutic devices for various injuries such as infected, ischemic and hypoxic wound. NIR-emitting technology has been developed recently in Korea. We hypothesized that NIR may have an anti-inflammatory effect and investigated the effect of NIR-irradiated media on cell culture. METHODS Three kinds of cell lines, CAPE...

Supernova (SN) 2006gy was a hydrogen-rich core-collapse SN that remains one of the most luminous optical supernovae ever observed. The total energy budget (> 2×10 erg radiated in the optical alone) poses many challenges for standard SN theory. We present new ground-based near-infrared (NIR) observations of SN 2006gy, as well as a single epoch of Hubble Space Telescope (HST) imaging obtained mor...

The detection of planets around very low-mass stars with the radial velocity method is hampered by the fact that these stars are very faint at optical wavelengths where the most high-precision spectrometers operate. We investigate the precision that can be achieved in radial velocity measurements of low mass stars in the near infrared (nIR) Y -, J-, and H-bands, and we compare it to the precisi...

We investigate the feasibility of trans-rectal optical tomography of the prostate using an endo-rectal near-infrared (NIR) applicator that is to be integrated with a trans-rectal ultrasound (TRUS) probe. Integration with TRUS ensures accurate endo-rectal positioning of the NIR applicator and the utility of using TRUS spatial prior information to guide NIR image reconstruction. The prostate NIR ...

A multispectral filter array (MSFA) image sensor with red, green, blue and near-infrared (NIR) filters is useful for various imaging applications with the advantages that it obtains color information and NIR information simultaneously. Because the MSFA image sensor needs to acquire invisible band information, it is necessary to remove the IR cut-offfilter (IRCF). However, without the IRCF, the ...
