Progress Report Towards A Digital Mirror Device Based Confocal Microscopic System

摘要：

　　It is widely believed that by using a digital mirror device(DMD)as the spatial light modulator(SLM)of a programmable array microcopy(PAM),it is possible to achieve a cost-effective alternative to expensive confocal imaging devices.During the past decade,the design of such a DMD based PAM instrument has been frequently reported to enhance resolution and contrast,convincing images with improved quality are rare to be seen.The concrete implementation of a DMD based PAM instrument needs to successfully resolve multiple issues such as the adverse effects caused by the tilt angle of the micro-mirrors from the base board,the registration between a micro mirror of the DMD and the image pixel of the photo-detector and so on.In this paper,we report the design of a middle body consisting of a DMD as an independent attachment to a conventional microscope to convert the latter into a confocal imaging system,in a similar way as a filter turret that is placed below the head and the objectives of a regular microscopy to convert it into a fluorescent microscopy.Images of real objects with improved contrast are provided to demonstrate the effectiveness of using a DMD as SLM to improve the contrast of a PAM instrument.Such a PAM instrument has many advantages compared to conventional laser-scanning confocal systems including lower costs and higher imaging speeds.In addition,it allows convenient dynamic adjustments between imaging quality and imaging speed.
