1. An image detection apparatus for use with a biological sample, the apparatus comprising:
- a light source that provides source light along a source light path;
a holding apparatus to hold a substrate, on which a biological sample is mounted, in a position such that at least a portion of the source light impinges on at least a portion of the biological sample and causes light emission representative of the biological sample to be produced in the form of emitted light along an emitted light path;
a light detector array comprising a plurality of detector pixels that is positioned in at least a portion of the emitted light path such that the array senses emitted light from the biological sample; and
a transport mechanism adapted to translate the light detector array to allow the capture of an image of at least a portion of the biological sample as a plurality of sub-images.

Abstract
An image detection apparatus comprises a light source and a holding apparatus adapted to hold a substrate on which a biological sample may be mounted. Light from the light source impinges on the biological sample and causes light that is representative of the sample to be emitted from the sample. A light detector is positioned in the path of the emitted light and is scanned across the emitted light. The emitted light may be focused on the light detector with an optical assembly. The emitted light may be generated by chromophores on probes in the biological sample.

7. An image detection system for use with one or more biological samples, the system comprising:
-
a light source that provides source light along a source light path;
a holding apparatus adapted to hold a substrate supporting a biological sample in at least a portion of the source light path such that the source light impinges on at least a portion of the biological sample, and produces emitted light representative of the biological sample along an emitted light path, wherein the source light path and the emitted light path are both on a first side of the substrate, and a light detector positioned in at least a portion of the emitted light path, and scannable across an image that is representative of the biological sample. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
