Therefore, when the sound field is present the beam is deflected and when it is absent the beam passes through undeviated.
2.
The Rochon prism was invented by and is named after S�narmont prisms the undeviated ray is ordinary on both sides of the interface.
3.
The exiting ray of the center wavelength is thus not only undeviated from the incident ray, but also experiences no translation ( i . e . transverse displacement or offset ) away from the incident ray's path.
