Electric field induced fluid flow on microelectrodes: the effect of illumination

The electrokinetic manipulation of particles suspended in a fluid medium is accomplished using microelectrodes that generate non-uniform fields of significant strength from low applied potentials. The high strength fields produce not only forces on the particles but also on the fluid medium used for suspension. This paper presents qualitative and semi-quantitative observations of the movement o...

The Dark Adaptation of the Eye of Limulus, as Manifested by Its Electric Response to Illumination

1. The phenomenon of dark adaptation of the eye of Limulus is reflected in the behavior of the action potentials obtained upon stimulation by light. The method of obtaining and recording these action potentials has been described in an earlier paper. 2. By determining the intensity of stimulus necessary to produce an electric response of a given magnitude (as to maximum action potential), at va...

SLM SLM illumination Reference illumination Holographic

A prototype reflective spatial light modulator (SLM) system has been developed for writing megabit pages of data into a holographic medium at a rate of 12 pages per minute. The SLM is based upon a crystalline-silicon reflective active-matrix array with integrated data drivers, using liquid crystal (LC) electrooptics and a personal computer system with an interface to provide data. The LC has be...

Illumination Invariants

In this paper we show how tools from group theory can be used to find invariants for time-changing illumination changes. In the first part of the paper we give a brief overview over the theory of one-parameter groups and their invariants. In the second part we describe how the chromaticity coordinates of time-changing illumination spectra can be described by one-parameter curves. Examples for b...
