Great answers guys! The line is most certainly created with a cylindrical lens in my case. Just out of curiosity, how is a line made with a diffraction pattern?
I gonna order some photo transistor components and a box to try the idea. I have doubts whether the laser line can be detected with...
Thanks, you're quick!
No moving parts, mechanics not my thing :-)
I'm not into optics that much either so I dont know how to design a diffuser from 50mm to 30mm2 sensor chip area but the idea intrigues me. Anyone got an idea?
Well I dont really need any sort of resolution, I only want to detect presence. I looked at some phototransistors but it seems that the chip area of them are small, such as this

It has an area of 0.29mm2 which roghly givs...
Thanks,
thats really helpful.
Do you know if these arrays of phototransistors also use some lenses or diffuser or similar? Or would you have to make a very tight packed array to not get any "dead" areas between the components?
Hi optics gurus,
I'm looking for a way to detect presence of a red or green laser line. If the laser line is within 50mm at least it should be detected. The sensor can be slow.
I thought about a construction laser line detector. How is the line detected there? Does anyone know what kind of...
I have a design with hierarchical blocks where one block is being instantiated several times (I believe this is a complex hierarchical design).
In this design I created a new page (in top level) where I pasted a simple circuit copied from an older design. The components gets auto annotated but...
