Optical Detectors and Receivers
Journal of Lightwave Technology, 1985In this paper, I will review the subjects of optical detectors and optical receivers. I will do this from both a historical perspective and looking ahead toward useful progress that may occur in the future. I will focus, at times, on the lessons learned while performing my own research and development activities, and on how and why the technology has ...

Optical detectors and receivers
1995An 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.

Astronomy differs from other branches of the exact sciences in certain essential ways. While physicists, chemists, geologists, and most other scientists are able not only to observe events in nature but also to interfere experimentally, experimentation is unavailable to the astronomer (if we make an exception of sending radio signals to the Moon and ...

Optical Receiver and Method for Receiving Optical Signals
The invention relates to an optical receiver comprising: An entry surface (15) being adapted to receive an optical signal (2) from a free beam, at least one optical fiber (10) being adapted to guide said optical signal (2), the optical fiber (10) comprising at least one core (18) having a first refractive index (nl) and a cladding (19) having a second ...openaire
Optical Detectors and Receivers
2004A signal undergoes an E/O transformation at a fiber optic transmitter and a corresponding O/E transformation at the receiver. This chapter discusses the O/E process, with emphasis on the first two blocks in that flow: the semiconductor optical detector, or photodiode, and preamplifier. The two together are referred to as the receiver's front-end.

OPTICAL RECEIVER FOR OPTICAL WIRELESS COMMUNICATION
2015Proposed is an optical receiver for optical wireless communication, comprising a light refraction device for refracting an incident light signal in order thus to split the incident light signal into partial light signals; a first converter device which comprises a plurality of first converter elements for coupling one of the partial light signals into ...
