A remote sensing platform for sensing a target may include a source configured to emit optical radiation toward the target. A device may be configured to dither the emitted optical radiation to alternately illuminate a number of locations on the target. A first detector may be configured to detect radiation reflected from a first location of the number of locations and to generate a first signal. A first lock-in amplifier may be configured to process the first signal. A second detector may be configured to detect radiation reflected from a second location of the number of locations and to generate a second signal. A second lock-in amplifier may be configured to process the second signal.
