A LIDAR system includes a receiver that includes a photodetector array configured to detect light and generate electrical signals based on the detected light; and a spatial light modulator having an array reflective elements, including a plurality of columns. Each column includes a plurality of reflective elements configured to switchably direct the light towards the photodetector array, where the spatial light modulator is configured to receive the light from objects in a field of view corresponding to ambient light reflected therefrom. The LIDAR system includes a controller configured to sequentially activate the plurality of columns of the spatial light modulator such that the plurality of reflective elements of an activated column directs the light towards the photodetector array; and at least one processor configured to receive the electrical signals from the photodetector array and generate a two-dimensional image that represents an ambient light picture of the field of view.
