get_rect()
Description: Creates a rectangular transducer. It is intended to work with the create_rect_array functions, but it can be used independently.
Usage
transducer = get_rect(width, height);
transducer = get_rect(width, height, center);
transducer = get_rect(width, height, center, euler);
Arguments
- width Width of the transducer in m.
- height Height of the transducer in m.
- center a 3x1 or 1x3 array with the center coordinate of the element.
- euler_angles a 3x1 or 1x3 array with the rotation of the element in radian. For details about how FOCUS handles Euler angles, see the documentation for rotate_vector_forward.
Output Parameters
- transducer A FOCUS transducer struct.
Notes
The weight of the transducer is set to 1 and the phase is
set to zero. If you need to focus via phase shifting, you must manually change the phase after the function has run.
