Title:
生体管構造を流れる流体の性状を決定する開口数可変の方法および装置
Document Type and Number:
Japanese Patent JP2007500529
Kind Code:
A
Abstract:
The present invention provides for an apparatus and a method for determining a property of a fluid which flows through a biological tubular structure, such as blood flowing through a capillary vessel ( 112 ) under the skin ( 114 ). This enables in vivo non-invasive blood analysis. An objective ( 108 ) having a variable numerical aperture ( 116 ) is used to enable automatic detection of a blood vessel ( 112 ) and to provide a high signal to noise ratio of the return radiation for the purposes of the spectroscopic analysis and to provide a small detection volume that fits completely within the target region.
