About this Research Topic
Photoacoustic detection features advantages both in optics and acoustics, shining the electricity, environment, medicine, biology, perimeter security, pipeline leak detection, and other fields. Photoacoustic effect can be simply addressed as the processing of light-induced sound waves. The progress in excited light source paves a promising way for photoacoustic techniques. Currently, the key devices of acoustic signal pickup are playing a vital role in photoacoustic detection. Whatever the MEMS devices, electric probe or optical microphone, all of these detected methods are facing the issues of low response sensitivity. Fortunately, with the advancement of laser processing technology, the optical-based acoustic probe is full of a huge amount of hope to accelerate the photoacoustic detection field to a higher level. At the same time, the progress of acoustic probe will shed new light on photoacoustic applications.
The recent advancement of photoacoustic techniques is mainly concentrated in the fields of multi-component trace gas detection, biomedical ultrasonic imaging, acoustic detection, and so on. For practical applications, the whole size of the photoacoustic devices should be continuously optimized to smaller and smaller. Particularly, the anti-resonant hollow core fiber regarded as the platform for light-matter interaction has gradually rivaled the traditional metal-based photoacoustic cavity. Here, the interaction region may appear in multi-physical fields evolution, such as optics, thermotics, and acoustics. As researchers strive to break through the limits of photoacoustic detection, new fields such as photothermic spectroscopy, and machine auditory technique, are further opened up, and challenges still exist in the field of photoacoustic. Therefore, in order to further promote the development of the depth of the interdisciplinary fusion between different technologies, improve the level of photoacoustic detection technology in the world of research and exchange the recent research achievements, discuss the photoacoustic detection technology and application development vision, the main goal of this Research Topic is to provide a platform for scientific and technological workers and related enterprises in the field of photoacoustic detection technology and application.
