Diffractive Wave Modulating Devices

View page
US Patent:
7099084, Aug 29, 2006
Filed:
Dec 1, 2003
Appl. No.:
10/707257
Inventors:
Baokang Bi - Okemos MI, US
International Classification:
G02B 27/44
G02B 26/02
US Classification:
359565, 359572, 359230, 359213
Abstract:
A zone plate modulator modulates an incident wave by changing the relative distance between a pair of complementary reflective zone plates. The modulator acts to reflect the incident wave as a plane mirror in a first configuration, and to diffract the incident wave into a series of focal points along the axis of the modulator as a phase zone plate in a second configuration. A force applied to the zone plates changes the zone plate modulator between the first and second configurations, therefore modulating the incident wave. The force can be an electrostatic force generated by a voltage source. An array of zone plate modulator elements is a compact spot array generator performing both the modulating and focusing functions. An achromatic zone plate modulator provides a both wavelength and polarization independent modulation of the incident wave. A variable optical attenuator comprises achromatic zone plate modulators.

Pattern Generating Systems

US Patent:
7227618, Jun 5, 2007
Filed:
Mar 24, 2004
Appl. No.:
10/708778
Inventors:
Baokang Bi - Okemos MI, US
International Classification:
G03B 27/54
US Classification:
355 67, 355 71, 355230, 355565, 355576
Abstract:
A pattern generating system for generating two-dimensional images on a surface includes a light source and one or more Zone Plate Modulator (ZPM) arrays. The ZPM arrays comprise diffractive zone plate modulating elements that are capable of either diffracting or reflecting an incident light according to the image data. In a high-resolution pattern generating system, ZPM arrays are used as spot array generators. A complete high-resolution image is formed by scanning individual light spots in the spot array using a subfield scanning means.

US Patent:
20030160542, Aug 28, 2003
Filed:
Jan 13, 2003
Appl. No.:
10/341514
Inventors:
Baokang Bi - Okemos MI, US
Brage Golding - DeWitt MI, US
Wen-Shin Huang - East Lansing MI, US
Jes Asmussen - Okemos MI, US
Assignee:
Board of Trustees of MICHIGAN STATE UNIVERSITY - East Lansing MI
International Classification:
H03H009/25
