Abstract: Systems and methods for standardizing one or more fluorescence scanning instruments to a reference system by separating the effects of drift and normalization. In an embodiment, a drift image comprising an image of a drift reference slide is captured by a system to be standardized. A drift measurement is calculated using the drift image. A first normalization image comprising an image of a normalization slide is also captured by the system to be standardized. A reference normalization image, also comprising an image of the normalization slide, is captured by a reference system. The first normalization image is compared to the reference normalization image to determine a gamma value and offset value for the system to be standardized.

Abstract: A spectral camera having an objective lens, an array of lenses for producing optical copies of segments of the image, an array of filters for the different optical channels and having an interleaved spatial pattern, and a sensor array to detect the copies of the image segments is disclosed. Further, detected segment copies of spatially adjacent optical channels have different passbands and represent overlapping segments of the image, and detected segment copies of the same passband on spatially non-adjacent optical channels represent adjacent segments of the image which fit together. Having segments of the image copied can help enable better optical quality for a given cost. Having an interleaved pattern of the filter bands with overlapping segments enables each point of the image to be sensed at different bands to obtain the spectral output for many bands simultaneously to provide better temporal resolution.
