Title:
励起システム及び焦点モニタリングシステムを備える分光分析装置及び方法
Document Type and Number:
Japanese Patent JP2006520900
Kind Code:
A
Abstract:
The present invention relates to an analysis apparatus, in particular a spectroscopic analysis apparatus, for analyzing an object, such as blood of a patient, and a corresponding analysis method. To aim the confocal detection volume inside a blood vessel orthogonal polarized spectral imaging (OPSI) is used to locate blood capillaries in the skin. An imaging system (img) with slightly shifted imaging planes (i1, i2) for OPS imaging of blood vessels is proposed to provide auto-focusing. The confocal Raman detection plane (dp) is located in between these two imaging planes (i1, i2). Based on measured amount of defocus for the imaging planes (i1, i2), the focusing of the imaging system (img), the excitation system (exs) for exciting the target region and the detection plane (dp) is located inside the blood vessel (V). Thus, continuous auto-focusing with high accuracy can be achieved. The invention relates also to an optical tracking system for continuously tracking a point of a moving object (obj).
