Holographic Airborne Rotating Lidar Instrument Experiment (HARLIE)

Class:

Instrument

Status:

Operational

Organizations:

The HARLIE transceiver is based on a volume phase holographic optical elements (HOE) made in dichromated gelatin (DCG) sandwiched between 2 layers of high quality float glass. It demonstrates the practical application of this technology to a compact scanning lidar system at 1064 nm wavelength. The HOE has the ability to withstand moderately high laser power and energy loading and is of sufficient optical quality for most direct detection systems,and overall efficiency rivaling conventional receivers. It's size and weight are approximately half of similar performing scanning systems using reflective optics.
