Distance Measurement Chips

[Acetronics2]

Hi Alain,

These days, I have been really strange (even to myself).

I guess I have not been able to focus on things precisely recently.

This may be a cause of me engaged to be married. I now have a fiancé.

That depends on what you mean by E.T. ?]

I didn't know your scheme ...

but remember measuring contactlessly short distances with a 1/3000 resolution is quite a nice piece of cake !!! ( the sonic way is very dependant of temp and humidity, and the light way ... is far too fast on such distances.)

why don't you want to build simple things ???

Alain,

This is not what I want to build. This is an inquiry that I want to catch and respond. I was thinking about laser ones but I have very limited time to do research on things.
Thanks to this forum and people like you. I can at least get some ideas so that I will know where and what to look for.

Well...another regular contributor soon to be gone from the list Unless this other person is a co-designer/co-programmer...

C'mon skimask,who can take us away from this forum?

BTW: Don't let my fiancé see this post, ok?

You can buy standard commercial devices that will do this like having a poo, they are used on machinery, and in hoppers, they can measure water level in a hopper full of steam if needs be, they use an infrared laser from memory they are around $300NZ and i think measure upto 10M with 1mm resolution
