Abstract
A system comprises an imaging device that includes a two dimensional array of pixels. Each pixel of the array includes a first optical filter having a first pass band arranged to filter excitation light reflected by a moving object and a first detector configured to detect light transmitted through the first optical filter and to generate a first electrical signal. Each pixel of the array also includes a second optical filter having a second pass band arranged to filter excitation light reflected by a moving object and a second detector configured to detect light transmitted through the second optical filter and to generate a second electrical signal. The imaging device further includes circuitry that generates output signals from each of the pixels based on the first electrical signal and the second electrical signal of the pixel. The output signal includes information about the speed and direction of the moving object.
