Abstract
Systems for and methods for in situ optimization of tunable light emitting diode sources are disclosed herein. During operation, the systems and methods obtain real-time feedback from an image sensor, and that feedback is used to tune the tunable LEDs. By tuning the tunable LEDs, the best values for the LED spectral output can be selected based on the feedback from the image sensor, and an image with improved contrast is obtained. Alternatively, the amount of time to obtain an image with acceptable contrast is reduced.
Claims13
A method comprising:
- receiving at least a first data set and a second data set from an image sensor, the first and second data sets being collected by the image sensor based on illumination of a sample using a tunable light emitting diode source having a plurality of tuning states corresponding to a plurality of illumination spectrums, wherein the first data set and the second data set are associated with a first tuning state associated with a first illumination spectrum and a second tuning state associated with a second illumination spectrum of the tunable light emitting diode source, respectively;
- generating a score image data set based on an optical computation applied to the first and second data sets;
- determining whether the score image data set satisfies a tolerance level;
- and
- generating a set of test data based on the score image data set when the score image data set satisfies the tolerance level.
