|
[001]-poled crystal of [100]1 x [010]2 x [001]3(A,P) cut as longitudinal mode transducer (33T). Said cut may also be used as transverse mode transducer (31T), i.e., [100]1(A) x [010]2 x [001]3(P). | |||||
Key on crystal designation / symbols:
- 011P and 001P indicate poling direction being [011] and [001], respectively, which is also the 3-direction.
- 33, 32 and 31 denote the mode of actuation/sensing, 33 being the longitudinal mode, and 32 and 31 are the transverse modes with the active direction being along the 2- and 1-axis.
- A, S and T denote actuator, sensor and transducer, respectively.
- 100L and 110L indicate the active length directions in [001]-poled crystals.
- Superscripts (A) and (P) next to directional axes denote the active and poling direction respectively.
