Abstract: An optical system a plurality of lenses, arranged within a same optical path, configured to simultaneously pass and focus therethrough short-wave infrared (SWIR) and mid-wave infrared (MWIR) spectral bands to a common focal plane and provide simultaneous correction of monochromatic and chromatic aberrations over the SWIR and MWIR spectral bands is disclosed. Another system and a method are also disclosed.

Abstract: A marine handling craft and system is intended for use in deploying, inspecting and receiving vessels and payloads to and from locations on, under, over or near water and wet soils in potentially turbulent aquatic or atmospheric conditions. The marine handling craft may operate as a robot, or deployed from a crane or boom on a mother ship or other platform or helicopter so that it can transport and mate and dock at various locations, such as supply ships or autonomous marine vessels, at a stand off distance to limit potential harm to valuable assets. A sliding fastener and track are included on the marine handling craft so that it can be tethered and lifted by a single line or cable, and so can be manipulated by a single crane or helicopter. The utility of the handling craft is not limited to the transport of payloads and it may function as a stand-alone vessel for various remote sensing purposes.
