Imagery

The IHFRI provides imaging (and spectral) information at a rate of 1000 frames per second for detection of ablation anomalies, flicker in bowshock emissions, spacecraft rotation, and wake.

This instrument consists of a 6 inch clear aperature f0.75/105 mm lens and 256 x 256 pixel intensified CCD camera. The field of view is 6.25 x 6.25 degrees, illuminating 11.5 x 11.5 mm of the photocathode of the intensifier. The intensifier phospher has a brief decay time constant of 0.8 ms, ideally suited to study the natural afterglow in rapidly moving targets. It can be equipped with a low dispersion 7 inch 300 l/mm grating, providing a spectrum from 500 nm (15.9 mm from zero order) to 900 nm (29.4 mm from zero order) just outside the field of view. Spectrum can be recorded by pointing away from the SRC and will help target acquisition by providing a ray directed to the zero order.

This pair of intensified cameras measure the total radiative output of the SRC during entry in the 400 - 900 nm band.

The INT instrument consists of four cameras, two on both sides of the aircraft, consist of a 50 mm f2.8 Nikon lens, an XX1332 image intensifier with large 48 mm photocathode, and a Sony handycam camcorder (recording of video output on Hi-8 tape in NTSC format - 640 x 480 pixels). The lens can be equipped with a low-dispersion grating to generate 1st and higher order spectra, each containing a fraction of the light. This facilitates the measurement of luminosity when the zero order image saturates.

ALLSKY is a wide field intensified camera with all-sky lens. It measures total radiative output in the 400 - 900 nm band.

This camera consists of a 15 mm f2.8 Canon lens, an XX1332 image intensifier with large 48-mm photocathode, and a Sony handycam camcorder (recording of video output on Hi-8 tape in NTSC format - 640 x 480 pixels). The field of view is about 160º when mounted so that the dome does not obstruct. Moonlight is blocked by covering the zenith part of the dome.

The Itek Iris II Panoramic Camera has been employed to acquire high resolution land use and land cover data. The Forest Service has used this camera extensively for assessing timber resources and monitoring gypsy moth defoliation in the Appalachian hardwood forests. The Iris II provides a 4.5 x 34.7 inch (11.4 x 88.1 cm) image covering 2.0 x 21.4 miles (3.2 x 34.2 km) on the ground. The high resolution twenty-four inch lens provides a scale at nadir on the panoramic image of half-mile to the inch. With its 10,000 foot film capacity the Iris II allows extended flight duration allowing photography acquisition over very large areas.

Provides spectral (and imaging) information at a rate of 1000 frames per second for detection of ablation anomalies, flicker in bowshock emissions, spacecraft rotation, and wake.

The instrument consists of a digital intensified CCD camera capable of 1000 frames per second, equipped with a 600 l/mm objective transmission grating.

Hycon HR-732 cameras are used to acquire high resolution photography in a 9 x 18 inch format. These cameras can be flown in pairs or one camera may be paired with an RC-10 mapping camera. The HR-732s acquire high resolution photography with twenty-four inch focal length lenses providing an image scale of half-mile to the inch. The large scale high resolution photography provided by these cameras is used by agencies such as the Forest Service for timber resource management and by the Fish and Wildlife Service for wetlands inventories and wildlife habitat mapping.

The Ames digital imager is a cooled large format NikonTM1 D70 digital camera with a 70-300mm f5.6 Nikon lens. It is used hand-held behind a passenger window with exposure times 1/1000s. The camera uses a SONYTM ICX413AQ CCD detector with image format 3040 x 2014 pixels of size 7.8 microns. It measures total radiative output of the sample return capsule along its trajectory.

The AIM-IT instrument (Meteor Tracker) was developed for rapid pointing and meteor tracking. Its purpose is to image bright meteors in high resolution, searching for jets and other plasma ejections. During the 2001 Leonids, the instrument carried a light collection lens with a fiber optic connection to a spectrograph.
