Abstract

The invention describes systems and methods for calibrating a low-level light imaging system. Techniques described herein employ a light calibration device that is placed within a low level light imaging box to calibrate the system and its constituent components such as the camera and processing system. The calibration device comprises an array of low-power light supplies each having a known emission. By taking an image of each low-power light supply, and comparing the processed result with the known emission, the accuracy of the imaging system and its absolute imaging characteristics may be assessed and verified.
