Sonographic detection of the optic radiation
Acta Paediatrica, 2005Abstract Objective: To describe a region of hyperechoic white matter adjacent to the atrium of the lateral ventricle of preterms, and to speculate on the relevance of detecting preterm white matter injury. Patients and methods: Cranial ultrasound images of 92 preterms of gestational age (GA) 32 wk or less were reviewed.

The Optical Detection of Platelets in Plasma
Thrombosis and Haemostasis, 1980SummaryThe attenuation of a light beam by a suspension of platelets in plasma was examined theoretically and experiments were performed to confirm this analysis. Interfering and modifying inputs were identified and their effects quantified. Recommendations for instrument design are made which minimise the effects of spurious inputs and enable platelet ...

Optical Fiber Communication Conference, 2014
In this paper we review the prior works on DDO-OFDM systems, including the traditional DDO-OFDM that utilizes single band and single polarization, the multiband DDOOFDM superchannel, and the dual-polarization (PDM) DDO-OFDM.

The detection and resolution of optical signals
IEEE Transactions on Information Theory, 1964Summary: The principles of statistical signal-detection theory are applied to the detection of optical signals by postulating the photoelectric effect as the mechanism for the interaction of the electromagnetic field of the light with matter. The data with which the detection system works are the numbers of photoelectric events in various parts of a ...

THE PULSED OPTICALLY PUMPED CLOCK: MICROWAVE AND OPTICAL DETECTION
Frequency Standards and Metrology, 2009We present theoretical and experimental studies concerning the realization of a rubidium vapor cell frequency standard based on the pulsed optical pumping (POP) technique. This technique is extremely powerful since it avoids in principle the light shift effect and the noise conversions from the laser to the clock signal.

Optical biosensors for detection of exosomes
Clinica Chimica ActaExosomes, nanoscale extracellular vesicles secreted by various cell types, have emerged as critical mediators of intercellular communication and valuable indicators of physiological and pathological states. Their stable presence in biofluids and ability to carry disease-specific molecular cargo make them ideal candidates for non-invasive diagnostics ...

Optical Fiber Sensors: Optical Detection
2000An optical sensor is a system in which some parameter characteristic of an optical signal is modulated in a reproducible and recoverable manner by a measurand. Although the transduction mechanism is optical, it is necessary to convert the optical signal to an electrical one in order that it may be processed and either recorded or displayed.
