Direct Phase Detecting System

Applied Optics, 1972
A system for extracting the phase components of an optical traveling wave field has been constructed. This system consists of the Mach-Zehnder interferometer to capture the wave field as the hologram, a photoelectronic scanning system, and an analog computing circuit.

Directional filtering in edge detection

IEEE Transactions on Image Processing, 1998
Two-dimensional (2-D) edge detection can be performed by applying a suitably selected optimal edge half-filter in n directions. Computationally, such a two-dimensional n-directional filter can be represented by a pair of real masks, that is, by one complex-number matrix, regardless of the number of filtering directions, n.

Detection of Direction of Contrast

1990
Abstract Because D.B., when he acknowledges having some sort of impression or feeling when a stimulus is abruptly presented, fails to ascribe any sense of ‘brightness’ to the experience — in fact, on one occasion he said, ‘it is as though I imagine that I am moving my finger in front of my eyes in the dark’ — it seemed possible that he ...

How to Detect Hayman Directions

Computational Methods and Function Theory, 2008
In order to answer the question in the title of this paper, the author introduces a class of \textit{Hayman exceptional functions}. He expects that it plays a similar role for the study of Hayman directions as Julia exceptional functions do for Julia directions, a characterization of meromorphic functions without any Hayman directions by means of this ...

On the Quantum Theory of Direct Detection

1997
By using the theory of measurements continuous in time in quantum mechanics [1][8], a photon detection theory has been formulated [9]– [12]; see Refs. [10]– [12] and [8] for detailed references. A quantum source as an atom, an ion or a more complicated system, eventually placed inside an optical cavity, is stimulated by lasers or by a thermal bath. The

On the “direct detection” of gravitational waves

Studies in History and Philosophy of Science
In this paper, I provide an account of direct (vs. indirect) detection in gravitational-wave astrophysics. In doing so, I highlight the epistemic considerations that lurk behind existing debates over the application of the term "direct". According to my analysis, there is an epistemically significant distinction between direct and indirect detections ...
