Imaging systems for signals on a surface
First Claim
1. An imaging apparatus comprising:
- (a) a holder for a surface, (b) a light source adapted to illuminate said surface, (c) a diffractive element between said holder and said light source, said diffractive element comprising an array of diffraction gratings wherein said diffractive element is arranged to sequentially illuminate different sets of features on said surface having a sample deposited thereon until substantially all of the features on said surface are illuminated and (d) an imaging detector adapted to receive light from said surface.

Abstract
Apparatus and methods are disclosed for imaging surfaces that comprise a sample. One embodiment of the present invention is an imaging apparatus comprising a holder for a surface, a light source adapted to illuminate the surface, a diffractive element between the holder and the light source and an imaging detector adapted to receive light from the surface. In a method for imaging a surface comprising a plurality of discrete features, light is selectively diffracted on to one or more predetermined features of the surface at a predetermined point in time. This step is repeated until substantially all of the features on the surface are illuminated. Light is detected from the surface to thereby image the surface.
