The sensor's active area (the large square region on the wafer) measures approximately four inches by four inches.

DALSA Semiconductor, a division of DALSA Corporation, announced today that it has successfully fabricated and delivered the world’s highest resolution image sensor chip to its customer, Semiconductor Technology Associates (STA) of San Juan Capistrano, California.
The CCD device, which measures approximately four inches by four inches, has a total resolution of over 111 million pixels (10,560 pixels x 10,560 pixels at 9µm). It is the world’s first imager to break the 100 million pixel barrier. STA developed the record-breaking chip for the Astrometry Department of the U.S. Naval Observatory (USNO), funded by the Navy’s Small Business Innovation Research Program. The device will assist USNO in the determination of the positions and motions of stars, solar system objects and the establishment of celestial reference frames. DALSA Semiconductor manufactured the device for STA at its wafer fabrication facility in Bromont, Quebec.
"As with past custom image sensor projects, I'm very satisfied with the versatility and capability of DALSA Semiconductor's foundry to collaborate on new process enhancements and to manufacture challenging custom CCD image sensor products such as this," commented STA President, Richard Bredthauer.

"I'm very pleased that we were able to deliver, ahead of schedule, this custom CCD image sensor to our long time DALSA foundry customer, STA," added Ralf Brooks, President of DALSA Semiconductor. "Completing this challenging, yet successful, project once again illustrates our strong process technology portfolio and our ability to work closely with our customers to create truly unique products."

Só gostava de saber o tamanho de uma imagem em modo raw á resolução maxima :-D:-D:-D

P.s. Joking

3,3GB a 32bit cor se ñ estou em erro ;)
Uma maquina tiha de ter, no minimo 4GB de ram só para abrir a imagem

EDIT: ..... never mind.... 430MB..... meti água nas contas.........

340 mb uncompressed 24bit , julgava que era bem mais

o standard é 24bits de cor
10,560 * 10,560 * 24bits = 2676326400 bits
(((2676326400 / 8) / 1024) / 1024) ~ 319MBytes

consegues gravar 2 fotografias num CD ^^ lol

impressionante..

Esse CCD é simplesmente muito grande. Deve ser uma colagem de outros como se costuma fazer noutros CCD "grandes"

Eu nem consigo perceber o tamanho (se é grande ou pequeno) pela foto...

É fácil de ver se olhares para o pixel pitch (também diz lá que é um quadrado de 4 polegadas)

De qq maneira fazer uma coisa destas é absurdamente caro mas isto também é só 1 sensor para um projecto especial
