Patent ID: 8722346

Claim:
A luminescence scanner apparatus for scanning a luminescent sample, the apparatus comprising: a sample bed; a detector bar configured to move with respect to the sample bed, the detector bar having one or more image sensor arrays, each image sensor array having a plurality of pixel elements; and a memory device and a processor operatively coupled with the detector bar, the memory device having instructions for programming the processor to perform operations for: moving the detector bar with respect to the sample bed in a first pass; taking a first set of pixel readings over predetermined exposure times during the first pass, each pixel reading of the first set occurring at a respective x, y position; moving the detector bar with respect to the sample bed in a second pass, the second pass being in an opposite direction from the first pass; collecting a second set of pixel readings over predetermined exposure times during the second pass, each pixel reading of the second set occurring at a respective x, y; and summing, using the processor, respective x, y position pixel readings between the first and second sets of pixel readings to construct an image.
