The spectroscopic analysis device and the method of having the excited system and the focus monitoring system

摘要

This invention analyzes object ones like the blood of the patient, it regards with the analysis method of corresponding with the analytical instrument which is the especially spectroscopic analysis device. In order to decide the aim in the confocal point detection volume which is inside the blood vessel, the spectrum image pickup (OPSI) which the orthogonal polarized light is done is used, position of the capillary in the skin specifies. The image pickup system (img) which has the image pickup plane surface which barely is shifted vis-a-vis the OPS image pickup of the blood vessel has proposed that the automatic focus adjusting is offered. Also focus Raman detection plane surface (dp), is placed between these two image pickup plane surfaces (i1 and i2). As for the excited system (exs) because the focus adjusting and the target territory of the image pickup system (img) are excited on the basis of the quantity where the focus end for the aforementioned image pickup plane surface (i1 and i2) is measured, and the detection system (dsy), in order because the aforementioned confocal point detection plane surface (dp) is placed inside blood vessel (v), to be equal to the quantity which established is done difference of the quantity of the aforementioned focus end adjusts. Because of this, always the automatic focus adjusting is achieved at high precision. This invention regards also the optical tracking system in order always to pursue the point of object ones (obj) which are moving.
