Appl. No.:

11/880736

Inventors:

Cynthia Lynne Lewis - Webster NY, US

International Classification:

G06F 19/00

US Classification:

702 77

Abstract:

A method for obtaining a modulation transfer function (MTF) of a knife-edge target imaged by an electro-optical device is described. The method includes the steps of: (a) obtaining edge response data points, where a data point includes a perpendicular distance, d, to the knife-edge target; and (b) constructing a sequence of line slopes of the edge response data points, where a line slope includes a spread of edge response data points. The method then selects a line slope that minimizes the spread of edge response data points, and calculates the MTF, based on the edge response data points included in the selected line slope. The MTF is provided to a user. An edge response data point is defined by a pair of values of (d, E) of a pixel, where distance, d, is the shortest distance between the pixel and a line slope and the pixel has an intensity value, E.

International Classification:

G02B 5/08

US Classification:

359846

Abstract:

The present invention relates to a system for modifying wavefronts of electromagnetic waves. The system includes a flexible mirror having an obverse surface and a reverse surface. The obverse surface has a contour configured to reflect the electromagnetic waves. The system also includes a plurality of actuators positioned along the reverse surface of the mirror for applying at least one transverse magnetic force to the flexible mirror to modify the contour of the obverse surface. Modifying the contour of the obverse surface of the mirror modifies the wavefronts of the electromagnetic waves.

Abstract:

A parallel plate wave-guide structure in a layered flexible/formable medium for transmitting complementary signals, including: at least two parallel signal conductor plates, placed in substantially close proximity, separated by a conductor-to-conductor dielectric material, and having a controlled impedance contained between the at least two parallel complementary signal conductor plates dominated by odd mode propagation of transverse wave components between the at least two parallel complementary signal conductor plates; at least two parallel reference plates forming a parallel plate reference system parallel to and surrounding the at least two parallel complementary signal conductor plates; dielectric materials that are contained between each of the at least two parallel complementary signal conductor plates and a corresponding parallel reference plate; a partial rectangular wave-guide structure comprised of the parallel plate reference system, such that each of the at least two parallel reference plates are electrically interconnected periodically.
