The very small aperture laser (VSAL) is a important light source used in the near-field optical storage system. So it is necessary for studying the near-field property of VSAL s output light.
The circuit substrate (100) is provided with an aperture region. As the speaker (2) is disposed on that region, a test sound wave is output to the moving section of the microstructure.
