Transparent ultrasound probe module and optical apparatus having the same

A transparent ultrasound probe module provided inside a housing of an optical apparatus, the transparent ultrasound probe module comprising:

• a lens provided on one side of an inside of the housing, formed of a transparent material, and disposed such that one surface thereof is exposed to the outside of the housing;
• a first matching layer provided on the other surface of the lens and formed of a transparent material;
• a piezoelectric element layer provided on the first matching layer and including a plurality of transparent piezoelectric elements capable of interconverting an electrical signal and a mechanical signal;
• a first electrode layer and a second electrode layer formed of a transparent material, provided on one surface and the other surface of the piezoelectric element layer, respectively, and configured to transmit an electrical signal;
• circuit boards connected to each of the first electrode layer and the second electrode layer, formed of a bendable material, and configured to transmit and receive the electrical signal to and from the piezoelectric element;
• and
• a block layer provided on the second electrode layer, formed of a transparent material, and configured to remove ultrasound noise.
