E-MAIL: Lisa M. Harvey, L.M.HARVEY@larc.nasa.gov. The Government intends to procure an Optical Position and Angle Measurement System, consisting of a multiple camera optical tracking system using active targets. The purpose of the system is to conduct accurate linear and angular position measurements of wind tunnel models in real time. The primary application: measure static and dynamic position and twist behaviors of wing models in the NASA-Langley Transonic Dynamics Tunnel. Quantity: 1 each A. The system shall be equipped with a minimum of two separate camera devices, consistent with the following requirements: 1. Camera heads shall contain crossed [orthogonal] linear CCD arrays. 2. Shall be capable of maintaining calibration during tunnel test series. 3. Shall have optics chosen and aligned to provide usable depth of field from 6 feet to 20 feet away from the camera heads. 4. Shall be capable of providing six degree of freedom results [x, y, z, and 3 angles], as acquired and computed from the active targets distributed in the field of view, at realtime video rates [60 Hz]. 5. Shall be capable of operating in adverse environments characteristically found in wind tunnel testing. 6. Shall have CCD sensors with high spatial resolution characteristics capable of resolving to 1 part in 50,000 or better. B. Shall be equipped with remote heads for the camera devices, which are dual axis sensors. These heads shall be packaged compactly [size not to exceed 8" x 6" x 3.5"], have a wide optical field of view [FOV], minimum of 30 degrees full angle each camera, and be environmentally packaged (to provide for thermal control and protection from water, dirt, and corrosion) for use in wind tunnels. These heads shall be delivered with protective storage/shipping case[s]. C. Shall have supporting camera bodies that are sealed units containing necessary support electronics and power supplies for the camera heads. Shall use standard sources for power at 120/240 VAC, 60 Hz. D. Shall be equipped with a system control unit that can carry out two successive rigid body transformations, based on up to 12 active target markers within the FOV, at rates up to 35 Hz. E. Shall be provided with processing and data buffering firmware that allow obtaining the six degree of freedom, real time video rate results required in Section A.4 above (to define and track rigid body motion in real-time -- 60Hz). F. Shall include at least 24 individual infrared light emitting diode (LED) markers, each mounted in a small base (0.25 inch diamter) with attached leads. Shall furnish 30 bare [unmounted] infrared emitting diode markers. G. Shall furnish three [3] 6-channel strobers with DB-9 connectors, which will operate the markers. Shall furnish power cords and other required peripheral items necessary for normal operation of parts mentioned in Paragraphs B, C, D, and E above. H. Shall furnish cables [strober, communications, and PC adapter interface cables] for operating the system with computer, control unit, cameras, and markers remotely located at distances of up to 100 feet. These cables shall accommodate placement of the computer, control unit, and the camera assemblies remotely at least 100 feet from one another; i.e., up to at least 100 feet between control unit and cameras, and up to at least 100 feet between computer and control unit. For lab testing, shorter cables are required, indicated in the following list. 1. Communications Cables: QTY TYPE 1 -- PC Interface Adapter Cable [short -- 6 inches] 2 -- 100 ft. Communications Cables [control unit to cameras] 1 -- 25 ft. Communications Cable [control unit to cameras] 2 -- 100 ft. Communications Cables [control unit to computer] 1 -- 25 ft. Communications Cable [control unit to computer] 1 -- 15 ft. Communications Cable [as needed, between cameras] 2. Strober Cables: [links to the active markers] QTY TYPE 1 -- 50 ft. Strober Cable [control unit to strober] 1 -- 25 ft. Strober Cable [control unit to strober] 1 -- 50 ft. Strober Cable [control unit to remote strober controller] 1 -- 50 ft. Strober Cable [remote control unit to strober unit] I. Shall have a "link repeater" to extend the length of communications link for up to 200 feet; shall have a remote strober controller to extend the operating distance of one strober port to a maximum of 125 feet. J. Shall include a three dimensional rigid calibration frame with a minimum of 16 markers mounted in precisely measured, fixed positions, the frame to be sized appropriately to permit accurate initial set up (to meet the requirements listed in paragraph A above, specifically A.6) K. Shall have a digitizing probe with six markers, all faced out on one side, calibrated relative to a tip, to permit accurately locating arbitrary points in the system FOV. Shall include necessary digitizing software. L. Shall be furnished with environmental conditioning components necessary to maintain the operation of the camera heads and sensor bodies [to include air filters, water taps, regulators/gauges, valve block assembly for shutoff, vortex coolers, and any other necessary items]. M. The system shall have all necessary computer interfacing hardware and complete software as follows: 1. Shall have interface card for Government-owned/furnished PC (IBM compatible). 2. Shall have the manufacturer s latest standard software for calibrating the system and for collecting and displaying data. 3. Shall have the manufacturer s latest version of application programmer's interface software for development of user-required applications. 4. Shall have manufacturer s latest version of software package for data analysis to perform various computations using the 3-D data and to provide graphical output. N. Three [3] sets of operating/maintenance manuals shall be provided. O. A 1-year warranty for parts and labor shall be provided. P. The item(s) acquired under this contract are required to include accurate processing of the date and date-related data including, but not limited to, calculating, comparing, sequencing, and the manipulation of data with dates prior to, through, and beyond January 1, 2000. This capability must be included in all hardware and software products delivered under this contract, individually and in combination, and shall be transparent to the user. Hardware and software products provided under this contract, shall individually, and in combination, be able to successfully transition into the Year 2000 with the correct system date, including leap year calculations, without human intervention.
