titleOfInvention |
Optically controlled ultrasonic sensor and method of manufacture |
abstract |
An ultrasonic probe optically coupled to an electronic console comprises a multiplicity of transducer elements. Each transducer element is capable of transmitting and detecting ultrasound waves. Each transducer element constitutes a piezocomposite structure comprising mutually parallel rods of two types embedded in a passive polymer matrix: piezoelectric rods and micro-cavity laser rods. The piezoelectric rods are optically activated to generate an acoustic compression wave transmitted from the front face of the piezocomposite structure. The micro-cavity lasers produce a frequency-modulated optical signal having a frequency shift which is a function of a strain produced in the lasing medium by a returning acoustic wave impinging on the piezocomposite structure. |
