Abstract: A method of implementing administrative services for managing group feedback is disclosed. A selection of a feedback visibility setting for a feedback message from a plurality of predefined feedback visibility settings is received via a give feedback tab of a user interface. The feedback message and a selection of one or more recipients are received via the give feedback tab. The feedback message is sent to the selected one or more recipients based on the selected feedback visibility setting. A request for feedback and a selection of one or more feedback providers are received via a request feedback tab of the user interface. The request for feedback is sent to the selected one or more feedback providers. Received feedback responses linked to a user profile of the feedback requestor are stored.

Abstract: A Mid-Wave Infrared (MWIR) objective lens having an F # of 2.64 and a 33.6° angular field of view. It is deployed, with a focal plane and scanning system, on an airborne platform for remote sensing applications. Focal length is 9 inches, and the image is formed on a focal plane constituting CCD or CMOS with micro lenses. The lens has, from object to image, three optical element groups with a cold shield/aperture stop. Group 1 has a positive optical power and three optical elements; Group 2 has a positive optical power and four optical elements; Group 3 has a positive optical power and three optical elements. The objective lens is made of two Germanium and Silicon. The lens is both apochromatic and orthoscopic, and corrected for monochromatic and chromatic aberrations over 3.3 to 5.1 micrometers.

Abstract: An orthoscopic, apochromatic lens is suitable for deployment such as on aerial platforms provides distortion less than 0.2% over a full field of view of more than 60° with F # less than 6.5 and focal length greater than 3?, and in embodiments greater than 5?. Embodiments are apochromatic from 500 to 950 nm to within 7 microns. Embodiments have an overall length of less than 7?. The lens includes five optical groups with an aperture stop between the second and third groups. The optical groups have one, one, two, one and one optical element each, as ordered from the object to the image plane, and have positive, negative, positive, positive, and negative optical powers, respectively. Embodiments are telephoto. In embodiments the focal length is temperature invariant within 0.0015 inches from 0° C. to 40° C.
