【発明の名称】光学検査用のディスク、光学検査の処理方法、及び光学検査システム
Document Type and Number:
Japanese Patent JP3364719
Kind Code:
B2
Abstract:
A system for conducting an optical inspection of a biological, chemical, or biochemical sample supported by an optical transparent disc, adapting a technology which has been developed in the field of audio and video compact discs to scan surfaces. The disc (44) is mounted for rotation about its central axis whilst a light source (37) and detector (38) are mounted on an arm (36) for rotation in an arc crossing the surface of the disc. The source (37) is arranged above the disc (44) and the detector (38) below the disc with the optical axes of the two being aligned so that' the entire useable surface of disc (44) can be scanned by the light source and detector. The disc (44) is provided with a calibration marking (49) which interrupts the passage of the light beam when the beam passes over it, thus allowing the scan to be aligned relative to the disc. The optical properties of the sample supported on the substrate can be automatically and rapidly inspected by analyzing the output of the light detector (38).
