Imaging the Universe with 3-D Holographic Gratings
31 Mayo 1999: Dr. Samuel Barden, astronomer at the National Science Foundation's National Optical Astronomy Observatories in Tucson, Arizona, has partnered with Mr. Willis Colburn and Mr. James Arns at Kaiser Optical Systems, Inc. (KOSI), Ann Arbor, Michigan for the development of large format spectroscopic gratings using holographic technology for astronomical applications funded by the National Science Foundation through the Advanced Technologies and Instrumentation Program in the division of Astronomy. These new technology gratings can provide information at multiple regions of the spectrum simultaneously, with higher efficiency, less cost, and greater durability than the conventional grating technology that astronomers have relied on for over a hundred years.
