System Use and Description
The EOI CDS differential temperature sources
create precise, adjustable thermal contrast patterns primarily in testing
and characterization of IR imaging systems.
The CDS Series features set point resolution of 0.01°C and stability
of ±0.003°C to ±0.010°C depending on the temperature. These exceptional capabilities enable accurate evaluation
of the most sensitive IR systems.
Configuration
These sources are available in stand alone configuration or integrated
into one of the many Target Projectors/Simulators and Automatic Test
Stations EOI offers. Source sizes (target area with 15°FOV) range from
1.8" x 1.8" to 14" x 14".
The optional MicroGroove® emitting surface provides a
significant improvement in effective emissivity.

Controller
Each Laboratory Differential Source is supplied with a 19" rack
mount digital controller. Operated manually from the front panel keypad or
automatically using any of the four built in computer interfaces, this
versatile controller also controls all optional equipment.

- Temperature Setting
- Control Mode Set
- Differential Mode
- Absolute
- Differential Mode
- Effective Differential
- Display Resolution
- K, °C, °F
- Remote/Local Control
- Ready Window Tolerance

Differential Temperature Mode
Temperature control of the thermal
contrast between controlled surface (source) and target.
Absolute Temperature Mode
Control of source at absolute temperatures.
Effective Differential Mode
Compensation for emissivity differences or losses in adjunct optical
systems so that zero differential temperature corresponds to zero
radiometric contrast.
Computer Interfaces
Complete computerized control of the system is available through
built-in interfaces.
- IEEE 488
- RS-232
- RS-422
- RS-485
All four interfaces are resident in controller. The IEEE 488 and any
one of the RS formats may be used at the same time.
Calibration
Each CDS200 System is calibrated at EOI
prior to shipment. Recommended calibration cycle is 6 months. Calibration
is traceable to  .
Calibration tables are stored in memory and are easily updated via the
front panel keypad.
Targets
An extensive list of standard four bar,
slit and circular targets is available. EOI also
supplies custom targets. Custom targets can be any pattern with minimum
dimension of 0.001" (0.025mm). |
