Mirage-H

Advanced Emitter Array
The fundamental component of the MIRAGE™-H scene projector is its advanced micro-emitter array. This state-of-the-art integrated circuit is constructed of thermally isolated mechanical structures with deposited thin film resistive heaters, fabricated on an advanced sub-micron silicon read-in integrated circuit (RIIC). Proprietary unit cell design minimizes thermal and electrical crosstalk.

Highly Integrated Digital Emitter Engine
The Digital Emitter Engine (DEE) is compact, lightweight and rugged designed for use on multi-axis motion simulators. The DEE comprises the emitter array and its support electronics, a vacuum dewar for the emitter, a heatsink for emitter cooling, local regulation for power supplies, a fiber optic receiver for scene data, and a precision kinematic mount for the optical interface. The lightweight and small size of the DEE make it the most compact IR scene projector available for FMS mounting.

High Gray-Scale Resolution for any UUT Integration Time
SBIR’s scene projection systems provide high gray-scale resolutions of 12 to 14 bits delivered to the user’s unit under test (UUT). This grayscale resolution is the same for any UUT integration time; or for variable integration times.

Automated Non-Uniformity Correction
Non-uniformity correction (NUC) is applied to each pixel in real time. SBIR’s C&CE supports an individual correction curve for each pixel, defined by 8 data points. Data for determination of those points is collected in the Calibration Radiometry System (CRS), an optional accessory for the scene projector which automates the process of NUC data collection. NUC can be done by the customer or purchased as an option from SBIR.

Built In Test (BIT)
An extensive BIT assures that the MIRAGE™-H system is functioning properly during use. BIT is automatically invoked on power up, and a continuous background (transparent to the user) BIT is performed during operation. Two levels of error are reported: error conditions that may damage the hardware will invoke an orderly hardware shutdown to protect the system; less serious errors are reported to the user, but continued operation of the system is permitted.

Graphical User Interface
A Windows™ graphical user interface provides a central control panel for system configuration and operation. The GUI automates the complex setup and sequencing of the instruments within the MIRAGE™-H system as it moves from its initial power-on state through real-time operation. The straightforward interface greatly reduces the load on the operator, prevents any inadvertent damage to the hardware, and provides continuous system status and built-in-test reporting. For users who want to control the MIRAGE™-H from their own facility control computer, a remote application programming interface is provided.
