System and method for improved optical measurements during rheometric measurements |
摘要 |
A rheometric system includes an optical encoder coupled to a rotating shaft and configured to detect a rotational position of the shaft with respect to a reference. The rotational information is forwarded to a program or memory. An optical rotation plate is mechanically fastenable to the rotating shaft. A laser is provided to probe optical properties of a fluid sample proximate to the optical rotation plate. The system includes a detector system for measuring laser light scattered or transmitted through the sample chamber. The detector system is coupled to a memory that stores optical data collected after light impinges on the optical plate. Experimental fluid sample optical data and background optical data are each stored as a data structure that creates a point by point map of rotational position of the sample plate with the optical data collected thereat. A program or routine is provided that can correct point by point along the optical rotation plate the experimental sample optical data using the background optical data.
