Systems and techniques for improving the dynamic range of infrared detection systems and for determining physical properties of a graybody are disclosed. For example, a mechanical superframing technique may comprise positioning a first set of filters in the optical path of an infrared camera at a first time, receiving infrared light from an object through the first set of filters at a detector array, acquiring first subframe image data for the object, positioning a second set of filters in the optical path of the infrared camera at a later time, receiving infrared light from the object through the second set of filters, acquiring second subframe image data for the object, and generating first superframe data based on at least some of the first subframe image data and at least some of the second subframe image data.
