项目摘要

The folloing researches were carried out to establish adaptive optics systems for high resolution observations :(1) Two workshops on "Wave Propagation in Turbulent Media and Adaptive Optics" were held in 1993 and in 1994 for three days each. These intensive workshops were very useful to promote collaborative researches among the resaerchers working in the related fields. The proceedings of this workshop will be printed in the Report of the Research Achievments.(2) Silicon avalanche photodiodes (APD) specially designed for use as low-noise wavefront sensors were fabricated and evaluated. The APDs used in the photon counting mode were proved to show high photon detection efficiency of 60%, short dead time of 200nsec, and low acceptable level of thermal background.(3) The image stablizer manufactured for use at the infrared Coude spectrograph of Okayama 188cm telescope was calibrated and the dome seeing monitor specially designed were manufactured.(4) Optical interferometer system was assembled and observation of double stars were made using an aperture masking method. Long term plans for optical and infrared interferometer were proposed.(5) Wavefront measurement and control to gain the efficiency of high power laser were studied.It is important to note that the present project yielded some collaborative projects among the researchers involved in this new field of science.
为建立适用于高分辨率观测的自适应光学系统,开展了以下研究工作:(1)分别于1993年和1994年举办了为期三天的“湍流介质中的波传播和自适应光学”研讨会。这些密集的讲习班非常有助于促进在相关领域工作的研究人员之间的合作研究。本次研讨会的会议记录将刊登在研究成果报告中。(2)制作并评估了专门用于低噪声波前传感器的硅雪崩光电二极管(雪崩光电二极管)。用于光子计数模式的APD具有高达60%的光子探测效率、200毫微秒的短死区时间和较低的热背景可接受水平。(3)对冈山188厘米望远镜红外耦合光谱仪中使用的稳像器进行了标定,并制作了专门设计的穹顶视宁仪。(4)组装了光学干涉仪系统,采用孔径掩膜法对双星进行了观测。提出了光学干涉仪和红外干涉仪的长远规划。(5)研究了提高高功率激光效率的波前测量和控制。值得注意的是,本项目在这一新兴科学领域的研究人员之间产生了一些合作项目。
