Untuk mengukur medan ultrasonik frekuensi tinggi yang sering diedarkan secara spatial dan sementara, probe tatasusunan dengan penderia elemen kecil sangat diperlukan. Dalam kertas ini, kami mencadangkan tatasusunan mikro-probe gentian optik yang berdasarkan teknik pemultipleksan pembahagian panjang gelombang. Penderia elemen terdiri daripada rongga optik mikro sepanjang 100 µm dibuat pada hujung gentian optik. Panjang laluan optik rongga diubah oleh medan akustik yang digunakan, dan modulasi keamatan cahaya keluaran dipantau pada hujung gentian yang lain untuk maklumat medan akustik. Susunan elemen penderia dan sumber cahaya serta pengesan foto disambungkan bersama oleh pengganding bintang optik. Panjang gelombang resonans Fabry-Perot bagi setiap elemen penderia direka bentuk berbeza antara satu sama lain, dan output daripada penderia didiskriminasi dengan menyapu panjang gelombang sumber cahaya dengan penggunaan laser semikonduktor boleh tala. Dalam kertas ini, prestasi tatasusunan kuar mikro dibincangkan secara eksperimen.

Abstract: For measuring high frequency ultrasonic fields which are often spatially distributed and transient, an array probe with small element sensors is highly required. In this paper, we propose a fiber-optic micro-probe array which is based on wavelength-division-multiplexing technique. The element sensor consists of a micro optical cavity of 100 µm long made at the end of optical fiber. Optical path length of the cavity is changed by the applied acoustic field, and the modulation of output light intensity is monitored at another end of the fiber for the information of the acoustic field. Array of sensor elements and a light source as well as a photo detector are connected together by an optical star coupler. The Fabry-Perot resonance wavelength of each sensor element is designed different one another, and the outputs from the sensors are discriminated by sweeping the wavelength of light source with the use of a tunable semiconductor laser. In this paper, the performance of the micro-probe array is discussed experimentally.
