Paper Abstract

Light emitting diode (LED) printbars are finding wider use as imaging devices in digital copiers and printers. The key to their acceptance in high quality printers requires tight control of the image plane irradiance profile. As a first step in understanding the imaging capabilities of an LED printbar a measurement system was developed to characterize the radiometric performance of the printhead from a slit scan of the image plane. From this scan of the image profile, statistics on the pixel to pixel irradiance, pixel to pixel placement, and pixel to pixel image size and shape are developed for an entire LED printhead.
