66 -- INFRARED ASTROMETRIC CAMERA SYSTEM SOL N00014-95-R-RS04 DUE 081195 POC Contract Specialist, Richard D. Sewell; Contracting Officer, John W. Adams,III; 601-689-8990. The Naval Research Laboratory has a requirement for a 1024 x 1024 Indium Antimonide (InSb) 0.7-5 micrometer Infrared Astrometric Camera (ASTROCAM) to extend the small angle astrometric capabilities developed at the U.S. Naval Observatory (USNO) to near infrared wavelengths using infrared array technology. Specifically, the required ASTROCAM will be used to investigate the accuracy and flux limits to which astrometry may be carried using large area infrared focal plane arrays. The ASTROCAM system will consist of the following components: (a) a government-furnished 1024 x 1024 InSb Aladdin array with 27-micron pixels; (b) re-imaging 1:1 Offner reflective optics with Lyot stop and baffles; (c) a closed-cycle cryocooled housing that maintains the Aladdin detector at 35 K, the optics at 77 K, and both enclosed in a 77 K or colder shield; (d) cold internal filter wheels, external stepper motors, and controllers to change filters and pupil plane reimaging optics; (e) a temperature control subsystem to permit both remote, computer control of array temperature and monitoring of array and cryostat temperatures; (f) an array electronics support subsystem providing functions which will include but may not be limited to bias voltages and level shifted clocking waveforms; (g) a data acquisition subsystem including preamplifiers, analog-to-digital converters, fiber-optic transceivers and links, and hardware/software necessary to synchronize conversions, format, transfer and store data; (h) a signal processing subsystem capable of performing co-addition of frames, fundamental image arithmetic, sample subtraction, and implementation of multiple sample noise reduction algorithms; and (i) a VME-based single board computer operating under the UNIX operating system to control all subsystems, to perform observing tasks issued via serial links by the host computer, and to provide processed data to the host via a high-speed link. The Government is seeking one (1) system. Detailed specifications will be included in the solicitation package. Prospective offerors should request, in writing, a copy of RFP/solicitation number N00014-95-R-RS04. RFP will be issued approximately fifteen (15) days after publication of this notice, with solicitation closing thirty days after issuance. Only written or telefaxed requests are acceptable. Telefax number: (601) 689-8960. All responsible sources responding to this solicitation will be considered. The Government will not pay for any documents or information received as a result of this notice or the associated solicitation package. (0193)
