Introduction. Susac’s syndrome consists of the clinical triad of cerebral microangiopathy, branch retinal artery occlusions, and hearing loss. The pathogenesis of the disease remains unknown. The severity of retinal vasculopathy remains variable. Case report. A 57-year-old Caucasian woman presented in 1999 for the diagnostic and therapeutic management of a severe and complete form of the disease. Fluorescein angiography and cerebral mrI were contributive in this case and confirmed the diagnosis. A severe unilateral visual loss occurred one month after the initiation of systemic corticosteroids. Funduscopy disclosed a temporal retinal artery occlusion with major ischemia. Therefore, cyclophosphamide and anticoagulants were added to corticosteroids and total visual recovery was achieved within 2 weeks without any relapse after a follow-up period of 54 months. Conclusion. Therapeutic management of Susac’s syndrome is still controversial. major immunosuppressive regimens are mandatory in the face of severe visual loss associated with central or branch retinal artery occlusions. The final prognosis of the disease seems favorable in the absence of prolonged and symptomatic retinal ischemia.

We demonstrate a compact heterodyne Laser Doppler Vibrometer (LDV) based on the realization of optical frequency shift in the silicon nitride photonic integration platform (TriPleX). We theoretically study, and experimentally evaluate two different photonic integrated optical frequency shifters (OFSs), utilizing serrodyne and single- sideband (SSB) modulation. Both OFSs employ stress-optic modulators (SOms) based on the non-resonant piezoelectrical actuation of lead zirconate titanate (PZT) thin- films, deposited on top of the silicon nitride waveguides with a wafer-scale process. To improve the modulation bandwidth of the SOms we investigate a novel configuration of the electrodes used for the actuation, where both electrodes are placed on top of the PZT layer. Using this top-top electrode configuration we report frequency shift of 100 kHz and 2.5 mHz, and suppression ratio of the unwanted sidebands of 22.1 dB and 39 dB, using the serrodyne and the SSB OFS, respectively. The best performing SOm structure induces 0.25π peak-to-peak sinusoidal phase-shift with 156 mW power dissipation at 2.5 mHz. We use the SSB-OFS in our compact LDV system to demonstrate vibration measurements in the kHz regime. The system comprises a dual-polarization coherent detector built in the PolyBoard platform, utilizing hybrid integration of InP photodiodes (PDs). High quality LDV performance with measurement of vibration frequencies up to several hundreds of kHz and displacement resolution of 10 pm are supported with our system.

对建于1994年的现代钢筋混凝土钟塔进行评估研究。此建筑具有独特的几何形状,高20m,宽0·40m。由于钟的摆动使塔受力所产生的动力交互作用,即使不用仪器也能清楚地被验证。1998年,借助于三维钢结构桁架,对钟塔结构进行加固,但加固后,仍然存在动力问题。因此,本文通过试验和数值分析对所产生问题的原因和程度进行研究。确定钟摆动对细长钟塔造成的动力问题,并推荐减小动力问题的措施。
