METHOD AND APPARATUS FOR RECONFIGURABLE FIELD OF VIEW IN A FAST-BASED IMAGING SYSTEM

摘要

A system and method to obtain a variable field of view (FOV) of a sample without requiring an increase in an imaging CCD array size. In a fiber array spectral translator (FAST) based chemical imaging system, the fibers in the fiber bundle may be organized in different 2D 'zones'. Each zone may include a predetermined number of fibers. Each 2D zone of fibers at the signal input end is organized as a separate linear array (ID) at the spectrometer slit input end. Depending on the user-selected FOV, one or more zones of fibers may be selected for signal input (into the spectrometer) by a motorized mobile slit port or linear translating stage, which will sequentially scan output from each selected linear fiber array into the spectrometer slit. The user can switch from one FOV size to another, thereby activating the linear translating stage.
