1. An optical interrogation system comprising:
- a tunable laser for generating an optical beam;
a first fiber launch for receiving the optical beam generated by said tunable laser and then outputting a first optical beam;
a first lens for collimating the first optical beam outputted from said first fiber launch such that the collimated optical beam illuminates a first biosensor;
said first lens for receiving a first reflected optical beam from the first biosensor;
a first detector, located ahead or past a focal point of said first lens, for receiving a first defocused optical beam from said first lens; and
a data processing device for receiving one or more intensity spot patterns associated with the first defocused optical beam received at said first detector.

Abstract
An optical interrogation system and a method are described herein that enable the interrogation of one or more biosensors which can be located within the wells of a microplate. In one embodiment, the optical interrogation system has a tunable laser, N-fiber launches, N-lenses and N-detectors that are set-up to interrogate N-biosensors. In another embodiment, the optical interrogation system has a tunable laser, N-fiber launches, N+1 lenses and N-detectors that are set-up to interrogate N-biosensors.

7. A method for interrogating one or more biosensors, said method comprising the steps of:
-
emitting a first optical beam which has a predetermined sequence of distinct wavelengths over a predetermined time period; using a first lens to collimate the first emitted optical beam such that the first collimated optical beam illuminates a first biosensor; using said first lens to receive a first reflected optical beam from the first biosensor; using a first detector to receive the first reflected optical beam from said first lens, where the first detector is positioned ahead or past a focal point of said first lens; and using a data processing device to receive a plurality of intensity spot patterns associated with the first reflected optical beam that was received at said first detector where each intensity spot pattern corresponds with one of the distinct wavelengths of the first emitted optical beam. - View Dependent Claims (8, 9, 10, 11, 12)
