技術摘要 / Our Technology:
一種影像探頭,適於伸入管狀待測物內,以感測管狀待測物內橫截面的影像,影像探頭包括光源激發組件、超音波發射器及接收器。光源激發組件包括脈衝雷射、第一光纖及錐狀反射元件。脈衝雷射適於發射脈衝光能量。第一光纖的第一入射端接收脈衝光能量,且脈衝光能量由第一光纖的第一出射端出射。錐狀反射元件適於反射由第一出射端出射的脈衝光能量,使脈衝光能量環形照射於管狀待測物的內壁,以產生光聲訊號。超音波發射器適於發射超音波訊號,超音波訊號環形照射於管狀待測物的內壁,以產生超音波回波訊號。接收器接收光聲訊號與超音波回波訊號。

An imaging probe is suitable to be inserted into a tubular object so as to detect an interior image of the tubular object. The imaging probe includes a light source excitation assembly, an ultrasonic transducer and a receiver. The light source excitation assembly includes a pulsed laser, a first optical fiber and a cone-shaped reflecting member. The pulsed laser is suitable to generate a pulsed light energy. The cone-shaped reflecting member is suitable to reflect the pulsed light energy to let the pulsed light energy annularly irradiate the inner wall of the tubular object so as to produce a photoacoustic signal. The ultrasonic transducer is suitable to generate an ultrasonic signal. The ultrasonic signal annularly irradiates the inner wall of the tubular object so as to produce an ultrasonic echo signal. The receiver receives the photoacoustic signal and the ultrasonic echo signal.
