Publication number: 20160187761Abstract: Methods, systems and apparatus for manipulating electromagnetic radiation such as laser beams include a first acousto-optic deflector optimised for efficient transmission at the input beam angle and a second acousto-optic deflector of lower peak efficiency than the first acousto-optic deflector but which accepts beams from a wider range of angles at better transmission efficiency than the first acousto-optic deflector by passing a beam optimised for efficient transmission through the first acousto-optic deflector at the input beam angle, deflecting the beam using the first acousto-optic deflector, passing the deflected beam through the second acousto-optic deflector, which has a lower peak efficiency than the first acousto-optic deflector and accepts beams from a wider range of angles at better transmission efficiency than the first acousto-optic deflector, and deflecting the beam using the second acousto-optic deflector.Type: ApplicationFiled: July 10, 2015Publication date: June 30, 2016Applicant: UCL Business PLCInventors: Paul Anthony Kirkby, K.

Patent number: 9104087Abstract: Methods, systems and apparatus for manipulating electromagnetic radiation such as laser beams. A method and apparatus for correcting magnification chromatic aberration utilizes one or more dispersive lenses such that long wavelength components are magnified less than short wavelength components. A telecentric relay is preferred to achieve this aim. Further, the use of polarizers to block the undesired zeroth order components of diffraction emanating from acousto-optic deflectors (AODs) is disclosed. Furthermore, specific designs of AOD including narrow transducer AODs which produce a diverging acoustic wave and AODs having two transducers and a selection switch are disclosed.Type: GrantFiled: February 10, 2014Date of Patent: August 11, 2015Assignee: UCL Business PLCInventors: Paul Anthony Kirkby, K.
