Laser-based Measurement Technique for Optical

Multi-Point In-Situ Profiling of Large Aspherics


Hardware- some of our development programs for unique requirements...........

Telescope alignment for the Chandra X-ray Observatory (CXO)

The Chandra X-ray Observatory (formerly known as AXAF) is now on orbit and delivering spectacular results. The X-ray images are the clearest x-ray images ever captured. To align the Chandra mirrors, Kodak contracted Bauer to design and manufacture the Centroid Detector Assembly (CDA), an electronic scanning Hartmann tester. The CDA was used first at Kodak to align the mirrors, and then at TRW to align the telescope to the Science Instrument Module interface. Positioned ten meters from the telescope, the CDA achieved a focal plane measurement accuracy of one micron, corresponding to a telescope resolution of 0.01 arc-second.

In-situ profiling of large aspheres

Bauer has executed a NASA Small Business Innovative Research (SBIR) Phase II contract to develop an instrument for absolute figure metrology of arbitrary aspheres to the nanometer level. This instrument promises to be an enabling technology for large astronomical programs such as the James Webb Space Telescope (JWST) and X-Ray projection lithography for semiconductor manufacturing.


Scanning, multi-wavelength photometer

The National Ignition Facility (NIF) requires a large quantity of superb, large optics with well understood performance. Bauer is under contact to deliver three scanning photometers to Lawrence Livermore National Laboratories (LLNL). These instruments will automatically map the polarization dependant reflectance and transmission of the flat and powered NIF optics to 1 part in 2000 at IR, visible and near UV wavelengths.

Golf swing tracking

Go Golf contracted Bauer to develop the Swing Dynamometer, which integrates optical and radar sensor data to provide real time tracking of golf swings. The three dimensional club position, as well as all angular orientations, are measured 5,000 times per second. The data is gathered and processed by a computer to provide immediate feedback to the golfer on any of a variety of selected swing parameters.

Bauer has also developed the Swingalyzer, a laser based, club mounted instrument that provides real time performance feedback for swing training.
