Research on depolarizing characteristics of a quartz depolarizer
2019 International Conference on Optical Instruments and Technology: Optical Systems and Modern Optoelectronic Instruments, 2020A depolarizer is usually used to reduce the polarization response of the spectrometer. On the basis of LYOT depolarizer, a depolarizer composed of two quartz crystals with the same wedge angle is designed and developed. Based on the matrix optics theory, this paper studies the relationship between the residual polarization degree of a LYOT depolarizer ...

The Depolarization Effect of Wedge Depolarizer for Polychromatic Light
2011 Symposium on Photonics and Optoelectronics (SOPO), 2011The wedge depolarizer was usually used as a depolarizer for monochromatic light, but the absolute monochromatic light is inexistent. In this paper, the depolarization effect of the depolarizer for polychromatic linearly polarized light with different spectrum types was discussed. The spectrum of incident light included Gauss, Lorentz and Rectangle. The

2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2019
Depolarization of EM waves in terrestrial communication links has been poorly researched. The main source of knowledge to this field comes from Stokes parameters and various field tests results. This paper presents an innovative analytical approach to this topic, providing a sufficient way of predicting the polarization of EM waves. This can be used to

Depolarization bandwidth of fiber optic passive depolarizers
Optical Engineering, 2001Several single-mode fiber optic applications benefit from the use of depolarized light. Examples are suppression of polarization hole burning (PHB) in erbium-doped fiber amplifiers (EDFA),1–3 reduction of polarization-dependent loss arising from fiber components (e.g., couplers and wave-division multiplexers),4 reduction of the signal fading in fiber ...

The depolarizing GABA response
Canadian Journal of Physiology and Pharmacology, 1997In some situations the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) elicits a hyperpolarizing response (H response) followed by a depolarizing response (D response) on cortical neurons. It has recently been established that the D response on hippocampal pyramidal cells is largely carried by bicarbonate ions (HCO3-).

Depolarizing the perceptual magnet effect [PDF]
The Journal of the Acoustical Society of America, 1998 In recent years there has been a great deal of interest in demonstrations of the so-called “Perceptual-Magnet Effect” (PME). In these studies, AX-discrimination tasks purportedly reveal that discriminability of speech sounds from a single category varies with judged phonetic “goodness” of the sounds.

The Ocean Radiometer for Carbon Assessment (ORCA), currently being developed at Goddard, is a hyperspectral instrument with a spectral range extending from 350nm to 880nm in the UV and visible wavelength. Its radiometric measurement accuracy will depend, in part, on the extent to which it is insensitive to linearly polarized light.

Depolarization-induced slow potentiation of depolarizing afterpotential
NeuroReport, 1997Effects of strong membrane depolarization on the excitability of regular spiking (RS) non-pyramidal cells in layer VI of the cat motor cortex were examined in in vitro slice preparations. RS non-pyramidal cells that expressed depolarizing afterpotential (DAP) following spikes displayed either of the two distinct responses: immediate and successive ...
