What happened to the inexpensive laser radar?

Hi all,
The Parallax 2009 catalog hinted at an inexpensive laser radar that was in development. I guess that it did not come to fruition. Oh well, maybe in 2010?

We're working with Joe Grand on this particular product. It's been a long-term development to say the least. The range will only be up to 40", but precision and accuracy are quite high.
I've seen working prototypes and soon we should put it in production.

I was hoping for more range, but I understand sometimes what we want is not equal to the monetary funds which it would require.
I personally was hoping in the range of 10's of feet.

i was hoping a skilled man would give it a shot.
Our laser range finder will use a CCD camera and laser point, fixed a few inches apart. Using trig we'll calculate the distance to the spot, based on where it appears on the sensor. The device you showed me is probably a time-of-flight + ultrasonic device.

Measuring range - 0.2 - 20m
0.2m nearest range, that's·about 8 inches, and nothing closer.
If that could be useful, you might be able to "read" (pick off, intercept) the data sent to the LCD (??).· Finding out how all that goes might be fun if you have a lot of time and desire -- or you're getting paid for it.
I am not sure that the device there has anything to do with ultrasonics though...
i've found another one with 1mm accuracy and range extended to 50m
I was thinking same as PJ Alen.. maybe something like reading the data sent to lcd.
Your laser finder will be working like this?

Recently i have totaly trashed an old working sony video camera. Along many interesting things i've got from it (like very small metal geared motors from zoom) i have found an interesting optical "device". Now the stupid questions follow:
Since the camera was very precise in autofocus, i was thinking that using the focusing optical ansamble (is made out of an phototransistor and another piece that i have never seen before, like a small photo sensor with 4 legs, the surface of this looks preaty much like a camera sensor looks like) might get an accurate distance measurement. The pcb that holds these 2 optical parts is quite small, it has 2 very powerfull lenses (one for each photo element) , and the signal is sent out in only one wire... the other 2 i have figured are just Vcc and Gnd.
I know this is not 'laser" at all, but it can work ?
Will it have a 3pin interface like the Ping)))?
Will it be compatible with all Microcontrollers?
Will the laser Need a external power supply?
I Would Absolutely LOVE to have one of these on my robot as soon as it comes out.

Accurate to +/- 1/16 inch with a range of 2" to 165 feet! And all with a laser <=1 mw. My mind boggles.
