Infrared scene projectors (IRSP) provide realistic dynamic inband imagery to the
unit-under-test (UUT) within the hardware-in-the-loop (HWIL) environment. These start-of-the-art
systems have begun transforming the manner in which infrared seekers may be evaluated in a
non-destructive laboratory environment. Optical Sciences Corporation provides the integration,
calibration, operation, and maintenance services in support of the AvMC dynamic infrared
projector systems. Optical Sciences Corporation also designs and manufactures several of the
projector systems used with the HWIL facilities. Each projector system is based on
state-of-the-art technology requiring a uniquely trained engineering staff to insure proper
calibration and operation. To date, these dynamic scene projectors have been successfully
applied to the closed-loop testing of several theater and tactical missile systems which employ
Emitter arrays are two-dimensional mosaic collections of thermal resistors. Infrared
scene projector (IRSP) systems based on emitter arrays are actively employed within the
AvMC HWIL test facilities. Historically, these devices have been manufactured
by two companies: Honeywell Technology Center(HTC) and Santa Barbara Infrared Corporation
(SBIR). HTC emitter arrays have been manufactured for a variety of applications and under
many model names. These models include: WISP, BRITE, CRISP, NODDS, DIRSP, and
MSSP. SBIR has manufactured emitter arrays under a single model name, MIRAGE.
Optical Sciences Corporation provides the integration, calibration, operation and maintenance
services required for the implementation of the HTC and SBIR emitter array based IRSPs employed
at AvMC's HWIL laboratories. OSC has developed extensive GUI-based system control
software packages for supporting these projector systems.
Example HTC Emitter Array IRSP Output Images
The following images were projected using an HTC emitter array based IRSP. The images were
subsequently collected using a commercial off-the-shelf MWIR InSb camera. Place mouse over

Example SBIR Emitter Array IRSP Output Images
The following images were projected using an SBIR emitter array based IRSP. The images were
subsequently collected using a commercial off-the-shelf MWIR InSb camera.
