Welcome to the Apple Support Communities
You should be able to use the iMac as a monitor. To do it, you need a Thunderbolt cable that you must connect on the Sony and the iMac > http://store.apple.com/us/product/MC913ZM/A/apple-thunderbolt-cable-2-m?fnode=51 Then, press Command and F2 keys on the iMac to turn on Target Display

thanks you for your quick reply.
I have look to the cable you mentionned but it seems to be radically different from the cable from sony z21 light peak.
The port we have in sony as for format usb but contains 2 rays of light !
Could you have again a look to my question: compatibility between imac target display throught thunderbold to light peak ?
Thanks again and happy new year!

In this case, you can't use it. Has that computer got any other connect for monitors? If not, you can't connect it to your iMac

Sony, as they tend to do, has implemented Light Peak very differently, even from Intel's own spec, and says that their own Power Media Dock is the only device capable of working with the Vaio's proprietary optical connection -- it will never work with Thunderbolt accessories, which would seem to include Target Display Mode of an iMac. So the answer, it would appear, is "no".

Thank you both of you.
In fact Sony seems to implement exactly the same specificattion as apple, the only different is that they used light cable and not copper cable. It add a small cost and better performance.
It is so shade that imac/sony are not compatible for this system.
Have a happy new year.

I have also HDMI output and VGA.
Do you think it could be used to display it to imac?
target display seems to be compatible only with thunderbold.

As there aren't any adapters to VGA and HDMI, you can't use them to connect the Sony to your iMac. I had heard some time ago that Sony was going to implement Light Peak on their computers and I thought that they were going to make them compatible with the Macs, but it looks like this wasn't true. I don't know if Apple has something to do with this

No, Sony combined the Light Peak technology with USB, very different from that of Apple's implementation. Sony themselves only call it a "docking station / USB port". You can read more about it here, if you wish:
Apple's Thunderbolt ports, by the way, can also use optical cable which, now that Intel has approved the spec, should start appearing from manufacturers in the near future, though I don't expect them to be cheap.
