Soft tape measure using optical linear encoder?

Postby goodwill1120 » Wed Oct 15, 2014 5:29 pm

Hi Chris,
Saw your optical linear encoder project, very interesting. A question for you- I have a project want to build an soft tape measure that would have accurate digital reading, if I can print a custom pattern on the tape with 1mm gap in between (like a zebra 1mm black, 1mm white), do you know where I can find a suitable 2 channel optical linear encoder available for such prototype which would be able to read on such material (usually nylon fabric printed) and has such a low resolution? (found something from avago which is 75 LPI but I don't believe I can get someone print in such resolution on the soft tape)
