Photoacoustic detection based on high sensitivity microsphere coupling

Not Accessible

Your library or personal account may give you access

Abstract

we use microsphere coupling with fiber (MCR) to detect photoacoustic signal and obtain noise equivalent pressures as low as 76 Pa with Q factor close to 102 * * * 6. And the MCR system can be as a platform used multiple times thought encapsulation of MY-133-MC glue.
