Embodiment Construction

[0015] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0016] The following descriptions are about the embodiments o...

Abstract

Embodiments of the invention provide a photoacoustic microscopy (PAM) system for observing an object. The PAM system includes an optical pickup head, an ultrasonic transducer, and an image generation unit. The optical pickup head emits a laser beam to the object, generates a servo signal based on a reflective light beam received from the object, and positions a focus of the laser beam onto the object based on the servo signal. The ultrasonic transducer detects laser-induced ultrasonic waves leaving the object to generate a PAM imaging signal. The image generation unit is coupled with the ultrasonic transducer and generates a PAM image of the object based on the PAM imaging signal. The photoacoustic microscopy system and related methods for observing objects can facilitate use of the photoacoustic microscopy system and reduce cost.

Description

technical field [0001] The present invention relates to photoacoustic microscopy (PAM), and in particular to PAM systems utilizing an optical pickup head as a light source. Background technique [0002] PAM is an imaging technique with vast potential applications. For example, it has been demonstrated that biological structures such as capillary can be observed label-freely, even in vivo, using PAM. [0003] Although PAM has the above advantages, it has not become a popular technology today. An important reason is that the most commonly used PAM systems utilize laser devices that are not only bulky but also expensive. The laser devices described above make conventional PAM systems inconvenient and less affordable. Contents of the invention [0004] In view of this, the present invention provides a photoacoustic microscope system and method for observing objects. [0005] A photoacoustic microscope system for observing an object, comprising: an optical pickup configured...
