Intensified High Frame Rate Imager

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.

Intensified Camera 1

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.

Intensified All-sky Camera

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.

High Frame Rate Slit-less Spectrograph

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.

Ames Digital Imager

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.

Automatic Meteor Tracker with Imager and Slit Spectrograph

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.

Thematic Mapper Simulator

This is a Daedalus AADS-1268 scanner that flies on the ER-2 aircraft and simulates the LANDSAT Thematic Mapper instrument, with slightly higher spatial resolution. The TMS is used for collecting data similar in application to data collected by the Thematic Mapper (TM) sensor including Earth resources mapping, vegetation/landcover mapping, and geologic studies.
