Can I use a reflective sheet other than LV-0012?

Ono Sokki provides HT-011 as a reflection mark for optical rotation detector or handheld digital tachometer. But HT-011 is not suitable for Laser Doppler Vibrometer because it has different structure, even if similar appearance as LV-0012.

 

Reason

A lot of microsphere glass beads are stuck on a reflection base material of LV-0012. Incident light is returned to direction of light source by those beads retro-reflective effect.

 

(About retro-reflective effect, refer to “What is the reflective mark (LV-0012)? “ in FAQ.)

 

Though same as LV-0012, HT-011 has a lot of microsphere glass beads on its reflection base material, furthermore, surface of HT-011 is coated. This coating causes reflection and distortion of a laser light in front of those beads, and reduces retro-reflective features of a laser light.  That’s why stable measurement is not possible.
