Photo-acoustic biomedical instrumentation will be a trend in the future. It uses very high sound frequency (in 100's of GHz) way above ultrasound range (1MHz to 18MHz). If there is anyone who is familiar with the technology, who is working with such a project, please let me know and give some of your ideas here.
Photo acoustic instrument is a very accurate in calculating the thermal parameters of a materials such as thermal diffusivity, conductivity and effusivity for the laser based device fabrications. i have an experience in working in this field . in what way i can help you?
Thank you M. Manivannan for your positive response. I need a clear idea how the technology works, how the light is manipulated to influence the sound, how the giga hz range sound frequency is achieved, and related IC or instrument design.
Sheryl Roberts , M. Manivannan , Subhamoy Mandal thank you foe your comment. Sheryl Roberts , thank you, I appreciate your suggestion, I will do that.
