We report on a study of a miniaturized laser module suitable for embedded projection with the flying spot approach. The module comprises RGB lasers, a closely connected laser driver ASIC and optical components. Key aspects of our studies are light output and color mixing stability as well as transient performance of the module.

We report on an intra image frame approach for controlling output power and mixed color of RGB lasers. Lasers, laser driving and laser control electronics as well as beam shaping and beam combination optics are components of a miniaturized module which is intended to be utilized in flying spot approach based mobile projectors. Key advantage of the introduced module concept is color stability across the whole image and the disappearance of flickering calibration lines at the top or at the bottom of the projected image.
