The optical interrogation technique can use an optical prism having two opposite sides including a sample side and a refraction side, the sample side having a plurality of interrogation areas; a source assembly generating a collimated field of illumination directed towards the refraction side; a screen disposed in a screen plane intersecting the field of illumination and shielding the refraction side from the field of illumination, the screen having an aperture allowing a portion of the field of illumination to reach and be refracted by the refraction side, be totally internally reflected at one of said interrogation areas of the sample side, thereby generating a signal, the signal refracted back through the aperture, the screen being movable within the screen plane to shift the aperture and expose different portions of the field of illumination to corresponding ones of the interrogation areas.
An optical interrogation system comprising:
A method of optically interrogating a plurality of samples or sample portions, the method comprising:
An optical interrogation system comprising a support configured to hold at least one sample, the support having a plurality of interrogation areas, a source assembly generating a field of illumination towards the sample support, the field of illumination spanning the plurality of interrogation areas and configured to generate a signal upon interacting with the sample, a detector assembly configured to receive the signal, and a screen disposed in a screen plane parallel to the interrogation areas, the screen having an aperture establishing an optical path specifically aligned with a corresponding one of the interrogation areas between the field of illumination and the detector assembly, at least one of the screen and the support being moveable in an orientation parallel to the screen plane to shift the optical path from one of the interrogation areas to another.
