(Digital values shown apply to the optional 14-bit digital data stream.)
The above ramp pattern repeats 19 times in the complete 320 × 256 image.
Note
The ramp test pattern is intended primarily for verifying the output of the digital data channel.
The pattern will not necessarily look as shown above when displayed on an analog video
monitor, particularly if an Automatic Gain Control (AGC) mode other than Automatic is
selected. The above image is a horizontal slice of the full displayed image.
Gain Mode:
The Tau camera has two gain ranges:
High gain mode is designed to maximize contrast for imaging applications.
Low gain mode has lower contrast but a higher dynamic range and is designed for
viewing hot targets.
Auto gain mode allows the Tau camera to switch between Low and High gain mode
based on the scene being viewed, Auto mode is controlled by the Gain Switch Values
in the Thermal tab. See "Thermal Tab" on page 3-28.
