Prototyping of a Biomedical Compact Disc Inspection System

摘要

The object of this paper is to discuss the basic design approach for a bio optical compact disc (BioCD) system, which has drawn extensive attentions within the biomedical industries during last decade. The related researches are becoming more valued due to a BioCD typical system usually integrates an optical focusing platform operated by piezoelectric actuators, well-managed micro-channels on the discs fabricated by semiconductor or micro-stamping manufacturing, an image processing mechanism for the collected fluorescence from the specimen reactions, and the highly developed optical disc driving mechanisms as well as the optic media coding technologies. In this paper, the basic principles of con-focal mechanisms and structure design of a BioCD system are stated first, and then followed with the inductions of a desktop as well as an embedded BioCD approaches. Essentially, both of introduced systems employ con-focal principles and piezoelectric actuators to design a three-group lens system, which is aimed to achieve fluorescence image amplification as well as optical slicing functions for the specimen. In the last, the collected slicing images of the specimen could be transmitted to an image processing mainframe, which is used to conduct certain pattern recognition and symptom identifications.
