Abstract

Autofocus is the key technology for automated microscopy.The velocity and accuracy of microscopy is dependent on autofocus methods.There are two types of autofocus technology,the passive type and the active type.The passive type is based on the digital image and the active one is based on the optical defocus error detection.By comparison the principles and development of the two types,it can be concluded that the active type based on the defocus error detection is more fast and accurate,which is more suitable for the automated microscopy.

显微镜自动聚焦方法研究综述

自动对焦是自动显微镜的关键技术。显微镜的速度和精度取决于自动聚焦方法。自动对焦技术有被动对焦和主动对焦两种类型。无源型基于数字图像，有源型基于光学离焦误差检测。通过比较两种类型的原理和发展，可以得出基于离焦误差检测的主动型更快、更准确，更适合于自动显微。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
