SAM = SOAR Adaptive Module

Improved angular resolution at optical and infrared wavelengths

Uniform and selective compensation of low-altitude turbulence

A relatively wide field (3 arcminutes)

Image quality improved by a factor of 2 to 5

Integrated CCD Imager

Correction achieved using a low-altitude Rayleigh laser guide star

Additional tip-tilt correction from two or one guide stars (R<18)

January 3, 2008. This is the status of the SAM bench being built in the shop. The front plate is missing in the picture, but it is 80% fabricated. The side plate is being built now.

March 5, 2007. A new SDN is available!! SDN-8307 on Tilt Error Signals has been uploaded. (PDF).

November 23, 2006. A new SDN is available!! SDN-3207 on NGS Wavefront Design. (PDF)

November 17, 2006. A new version of the SAM Optical Alignment has been uploaded. Team members comments are welcome! (PDF)

October 31, 2006. The mechanical design of the SAM bench is nearly finished. The mock-up bench is used to trace the cabling and to check access for alignment [click to enlarge].
