1. An interrogation system comprising:
- a tunable laser that has a tuning range wherein an optical beam is emitted therefrom which has a predetermined sequence of distinct wavelengths over a predetermined time period;
illumination optics that converts the optical beam into one or more interrogation beams which illuminate one or more biosensors;
imaging optics that collects an image from the illuminated one or more biosensors;
a 2-D imaging device that obtains a sequence of the collected images each of which corresponds with one of the distinct wavelengths of the optical beam emitted from said tunable laser; and
a data processing device that receives the collected images and processes the collected images to;
determine whether or not there was a biochemical interaction on each of the one or more biosensors;
locate sensor region(s) and/or reference region(s) on each of the one or more biosensors;
remove defect regions on each of the one or more biosensors; and
/orcalibrate a uniformity of surface chemistry and target molecule immobilizations on each of the one or more biosensors.

Abstract
A swept wavelength imaging optical interrogation system and a method for using the same to interrogate one or more biosensors are described herein. The swept wavelength imaging optical interrogation system is built upon a swept wavelength optical interrogation technology where a 2-D label free image is extracted from a series of high speed spectral images of the biosensor(s) without the need of performing mechanical scanning.
