Due to the rapid acceleration in technology and the drop in costs, the use of commercial off-the-shelf (COTS) PC-based
hardware and software components for digital and hardware-in-the-loop (HWIL) simulations has increased. However,
the increase in PC-based components creates new challenges for HWIL test facilities such as cost-effective hardware and
software selection, system configuration and integration, performance testing, and simulation verification/validation.
This paper will discuss how the Digital Video Timing Analyzer (DiViTA) installed in the Aviation and Missile
Research, Development and Engineering Center (AMRDEC) provides quantitative characterization data for PC-based
real-time scene generation systems. An overview of the DiViTA is provided followed by details on measurement
techniques, applications, and real-world examples of system benefits.
The Micromirror Array Projector System (MAPS) is an advanced dynamic scene projector system developed by Optical
Sciences Corporation (OSC) for Hardware-In-the-Loop (HWIL) simulation and sensor test applications. The MAPS is
based upon the Texas Instruments Digital Micromirror Device (DMD) which has been modified to project high
resolution, realistic imagery suitable for testing sensors and seekers operating in the UV, visible, NIR, and IR
wavebands. Since the introduction of the first MAPS in 2001, OSC has continued to improve the technology and
develop systems for new projection and Electro-Optical (E-O) test applications. This paper reviews the basic MAPS
design and performance capabilities. We also present example projectors and E-O test sets designed and fabricated by
OSC in the last 7 years. Finally, current research efforts and new applications of the MAPS technology are discussed.

The Micromirror Array Projector System (MAPS) is a state-of-the-art dynamic scene projector developed by Optical Sciences Corporation (OSC) for Hardware-In-the-Loop (HWIL) simulation and sensor test applications. Since the introduction of the first MAPS in 2001, OSC has continued to improve the technology and develop systems for new projection and test applications. The MAPS is based upon the Texas Instruments Digital Micromirror Device (DMD) which has been modified to project high resolution, realistic imagery suitable for testing sensors and seekers operating in the UV, visible, NIR, and IR wavebands. This paper reviews the basic design and describes recent developments and new applications of the MAPS technology. Recent developments for the MAPS include increasing the format of the micromirror array to 1280x1024, increasing the video frame rate to >230 Hz, development of a DMD active cooling system, and development of a high-temperature illumination blackbody.

Recent developments for the MAPS include increasing the format of the micromirror array to 1024x768 and increasing the binary frame rate to 10KHz. The MAPS technology has also been applied to the design of a Mobile Extended Spectrum Electro-Optical Test Set (MESEOTS). This test set is designed for testing UV, visible, NIR and IR sensors as well as laser rangefinders, laser trackers, and laser designators. The design and performance of the improved MAPS and the MESEOTS are discussed in paper.
Optical Sciences Corp. has developed a new dynamic infrared scene projector technology called the Micromirror Array Projector System (MAPS). The MAPS is based upon the Texas Instruments Digital Micromirror DeviceTM which has been modified to project images that are suitable for testing sensors and seekers operating in the UV, visible, and IR wavebands. The projector may be used in several configurations which are optimized for specific applications. This paper provides an overview of the design and performance of the MAPS projection system, as well as example imagery from prototype projector systems.
