Abstract: A densitometer includes a plurality of light-emitting diodes (LEDs) and at least one sensor. The LEDs are activated one at a time in a sequential, repeatable order. Photonic energy from each LED is reflected off an entity and is incident upon the sensor(s). Circuitry samples or acquires signaling from the sensor(s) in accordance with the respective LED activations. Signaling from the densitometer can be used in controlling ink-jetting printers or other apparatus.
