In acousto-optics, the electrical signal does not directly impact the index of refractionand therefore within this more selective interpretation “acousto-optics” is often treated as adistinct specialty area within the field of optical engineering. A wide range of applications existfor acousto-optic devices which include laser beam deflectors, ultrasonic imaging, Q-switchingfor pulse generating lasers, real-time signal processing, a plethora of radar applications, andtunable optical filters.

Also, during the second step, the instructor joined the students'conversations, and it provided the opportunity for all of the students to interact with theirprofessor in the format of a discussion rather than a formal Q and A practiced in the standardlecture classes. The students were asked to explain their solutions or their approach to solving theproblems to each other so they would exchange ideas and get exposed to different ways ofsolving a problem.

Proponents believe it is an inevitable trend inengineering undergraduate education, which brings deep learning to realization. Because coursecontent is digitized and posted online in “flipped classrooms”, in-class periods now can be usedfor interactive and purposeful activities.
