Using DLP with a laser source-- I want to measure the location of the contact point and associated angles of attack when a cue tip hits the cue ball

Jozef Sliwkowski

As part of a high school senior project I am trying to measure the contact point and angle when a cue tip makes contact with a cue ball.

My thought is to use a range-finder type laser and scan the expected surface area where the contact is made

Will need two such devices to get the plane of the cue tip and the location of contact with the cue ball.

Questions:

1) Can I use a TI optical mirror device with a laser at all

2) What is the time it takes to turn a mirror on or off

3) Is the mirror's position binary or can it be more finely controlled?

Would appreciate some answers that then give me a starting point for further specifying my requirement

Hi Jozef,

Thanks for posting your question. Here is some more information:

1) Take a look at this white paper: Using Lasers with DLP® DMD technology (www.ti.com/.../dlpa037)

2) This can vary by Digital Micromirror Device (DMD). The DLP3000's mirror switching time is 16 us, which is listed in the datasheet (www.ti.com/.../dlp3000) found on the DLP3000 DMD page (www.ti.com/.../dlp3000). We have other DMD offerings as well

3) It's binary. You can take a look at the datasheet above or other DLP literature (www.ti.com/.../technical-documents.page) for more information. Specifically, our DMD 101 application note may be of interest (www.ti.com/.../dlpa008)

Thanks,
Clinton
