User Manual for the Thermographic System VarioCAM

3. Technical Description

Opto-mechanics

The following functions are performed with the help of the opto-mechanics assembly group:

■

Focussing (motor focus)

■

Effective range change-over (lens apertures)*

■

Internal NUC (Non Uniformity Correction) using an internal shutter

Furthermore, this assembly group has an optional module for a hardware-based increase of geometric

resolution of the thermographic system onto (768 x 576) IR pixels (detector of [384 x 288] pixels) and

onto (1,280 x 960) IR pixels (detector of [640 x 480] pixels): mode "Resolution Enhancement"*. The opto-

mechanics can be modified for reducing the minimal focus distance*.

Controls

VarioCAM

hr head is mainly designed for stationary applications. For those case of operation the

camera is operated from a host computer, via the FireWire (IEEE 1394)-Interface of the device. The

relevant operating software is also described in Chapter 8 Hardware and Software Installation for

VarioCAM® hr head* – page 5.

Power supply

The VarioCAM

hr head has the following power supply options:

■

External power supply unit 12 V*

■

FireWire (IEEE 1394) interface*.

The mains adapter is connected to the 14-pin (left) socket at the rear of the camera.

For devices equipped with a FireWire (IEEE 1394) interface, the supply voltage can be taken directly from

the PC interface card. Please note the specification of the used interface card and the power input of the

thermographic system. In case of cable lengths > 5 m, power should principally be supplied via the

external power supply unit or the rechargeable battery.
