Abstract:
1. A method of strobe illumination for acquiring an image of an object, comprising: operating a first respective light source according to a first respective light pulse pattern including at least one light pulse while acquiring the image, the first respective light pulse pattern having an overall strobe duration period defined between a start of a first light pulse of the first light pulse pattern and an end of a last light pulse of the first light pulse pattern; and operating at least a second respective light source according to a second respective light pulse pattern while acquiring the image, the second respective light pulse pattern including at least one more light pulse than the first light pulse pattern, the light pulses of the second respective light pulse pattern distributed over a portion of the overall strobe duration period; wherein the respective first and second light pulse patterns at least partially govern the respective time-averaged intensities provided by the respective first and second light sources while acquiring the image.
