Publication number: 20090096882Abstract: Systems and methods include optics having one or more phase modifying elements that modify wavefront phase to introduce image attributes into an optical image. A detector converts the optical image to electronic data while maintaining the image attributes. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets, and independently processes the data sets to form processed electronic data. The processing may optionally be nonlinear. Other imaging systems and methods include optics having one or more phase modifying elements that modify wavefront phase to form an optical image. A detector generates electronic data having one or more image attributes that are dependent on characteristics of the phase modifying elements and/or the detector. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets and independently processes the data sets to form processed electronic data.Type: ApplicationFiled: April 3, 2007Publication date: April 16, 2009Applicant: CDM OPTICS, INC.Inventors: Gregory Johnson, Edward Dowski, Kenneth Kubala, Ramkumar Narayanswamy, Hans Wach

Patent number: 7319783Abstract: A method for reducing optical distortion within an optical system employing adaptive optics, includes modifying phase of a wavefront of the optical system with a wavefront coding element. Image data of the optical system is post-processed to remove phase effects induced by the wavefront coding element, to reduce optical distortion caused by the adaptive optics and associated with one or more of quilting, stuck actuator and piston error.Type: GrantFiled: November 17, 2006Date of Patent: January 15, 2008Assignee: CDM Optics, Inc.Inventors: Edward Raymond Dowski, Jr., Kenneth Scott Kubala, Alan Eugene Baron

Publication number: 20070247725Abstract: Zoom lens systems and methods for imaging incoming rays over a range of ray angles are disclosed. The incoming rays are characterized by at least phase. The zoom lens system includes an optical axis and is characterized by a plurality of modulation transfer functions (MTFs) corresponding at least to the range of ray angles. The zoom lens system includes an optical group disposed along the optical axis, including at least one variable optical element that has a variable focal length selectable between at least two distinct focal length values. The optical group also includes a wavefront coding element. The wavefront coding element alters at least the phase of the incoming rays, such that the plurality of MTFs corresponding to the range of ray angles, for each one of the two distinct focal length values, are less sensitive to misfocus-like aberrations than a corresponding system without the wavefront coding element.Type: ApplicationFiled: March 6, 2007Publication date: October 25, 2007Applicant: CDM OPTICS, INC.Inventors: Edward Dowski, Satoru Tachihara, Robert Cormack

Patent number: 7260251Abstract: An imaging system for reducing aberrations from an intervening medium, and an associated method of use are provided. The system may be an optical or task-based optical imaging system including optics, such as a phase mask, for imaging a wavefront of the system to an intermediate image and modifying phase of the wavefront such that an optical transfer function of the system is substantially invariant to focus-related aberrations from the medium. A detector detects the intermediate image, which is further processed by a decoder, removing phase effects from the optics and forming a final image substantially clear of the aberrations. Other systems may employ an encoder that codes wavefronts of acoustical waves propagating through a medium to make the wavefronts substantially invariant to acoustical aberrations from the medium. Imaging and decoding of the wavefronts reverse effects of the wavefront coding and produce sounds substantially free of the aberrations.Type: GrantFiled: March 31, 2004Date of Patent: August 21, 2007Assignee: CDM Optics, Inc.Inventors: Edward Raymond Dowski, Jr., Kenneth Scott Kubala, Alan Eugene Baron

Patent number: 7180673Abstract: An optical system with mechanical adjustment provides for the rotation and/or translation of one or more optical phase filters to variably select an extended depth of field, aberration-tolerance, and/or anti-aliasing properties of an optical imaging system. By adjusting the amount of phase induced on the wavefront, a user may select image quality selectively. The system may further automatically counter change of focus and/or aperture to maintain substantially constant image properties. Typically, two phase filters are used and moved concurrently to achieve desired image properties.Type: GrantFiled: March 25, 2004Date of Patent: February 20, 2007Assignee: CDM Optics, Inc.Inventor: Edward Raymond Dowski, Jr.

Patent number: 7089835Abstract: A method and control system for forming workpiece surfaces with at least a portion being non-rotationally symmetric (i.e., axis asymmetric) is provided. In one aspect, a slow tool servo system is provided to fabricate a surface having at least an axis asymmetric portion, and optionally, a superimposed axis symmetric asphere or spherical portion. A workpiece is mounted on a spindle and a tool is mounted to a translatable tabletop surface. The z position of the contact point of the workpiece and working tool is determined as a function of the x position of the same contact point and as a function of the angle of rotation of the spindle about the spindle axis. By making the z position of the contact point a function of both the angle of spindle rotation and the x position, the lateral and longitudinal position of the working tool can be moved at designated spindle rotation angles to form a surface having both axis asymmetric and axis symmetric asphere or spherical portions.Type: GrantFiled: July 2, 2003Date of Patent: August 15, 2006Assignee: CDM Optics, Inc.Inventor: James B. Bryan

Patent number: 7088419Abstract: An optical lithography system that has extended depth of focus exposes a photoresist coating on a wafer, and includes an illumination sub-system, a reticle, and an imaging lens that has a pupil plane function to form an aerial image of the reticle proximate to the photoresist. The pupil plane function provides the extended depth of focus such that the system may be manufactured or used with relaxed tolerance, reduced cost and/or increased throughput. The system may be used to form precise vias within integrated circuits even in the presence of misfocus or misalignment.Type: GrantFiled: June 1, 2004Date of Patent: August 8, 2006Assignee: CDM Optics, Inc.Inventors: Edward Raymond Dowski, Jr., Gregory E.

Patent number: 6842297Abstract: Improved Wavefront Coding Optics, which apply a phase profile to the wavefront of light from an object to be imaged, retain their insensitivity to focus related aberration, while increasing the heights of the resulting MTFs and reducing the noise in the final images. Such improved Wavefront Coding Optics have the characteristic that the central portion of the applied phase profile is essentially flat (or constant), while a peripheral region of the phase profile around the central region alternately has positive and negative phase regions relative to the central region.Type: GrantFiled: August 31, 2001Date of Patent: January 11, 2005Assignee: CDM Optics, Inc.Inventor: Edward Raymond Dowski, Jr.
