3 Camera Features and Functions The FLIR AIS Tau CNV (see Figure 1) is an ultra-low light and small form factor video camera with user programmable gain and on-chip electronic shuttering that provides large dynamic range and image processing features that make it suitable for full sunlight to overcast starlight applications.
The Tau CNV supports noise suppression using image subtraction techniques. Noise suppression allows frame-to-frame noise to be filtered out to improve image quality, especially for low-light imaging applications. The amount of noise suppression is programmable (see Tau CNV ICD). Note: This use of noise suppression can cause image-lag in dynamic scenes.
3.6 Integrated, Motorized, IR Cut Filter Option The Tau CNV color camera can be purchased with an integrated, motorized, IR-cut filter option. The lens mount assembly hosts a motorized two-glass position filter slider mechanism: (1) a BG38 IR-cut filter for daytime operation to preserve accurate color representation, and (2) a clear glass filter that is used for low-light imaging applications.
3.9 Digital and Analog Video Output Options The Tau CNV provides both digital and analog video output. The digital output is a NUC corrected RGB video output and is available using the Parallel or Camera Link interface. The analog video has NUC, color, white balance and contrast corrections (as enabled) and is available in NTSC or PAL (future) formats on the Group Interface and on the Parallel Interface.

The filter is controlled manually using serial commands, or under automatic control for detected low-light conditions. The default operation is manual control. Figure 4: Tau CNV Camera with M42 Lens and C-Mount Adapter 2011 FLIR Advanced Imaging Systems...
Figure 5: Tau CNV Camera with M42 Lens Mount, Integrated IR-Cut Filter Slider (color only), and C- Mount Adapter 5.3 Tau CNV CMOS Sensor The FLIR AIS Tau CNV is based on a high dynamic range Scientific CMOS (sCMOS) imager technology.
The sensor mount also includes a tapped ¼-20 tripod adapter mounting hole, and the tripod adapter can be procured from FLIR. See section 7 for the mechanical mounting information and section 8 for camera mounting & cooling information.
The Tau CNV has two interface types: (1) The parallel interface; and (2) the group interface. The parallel interface is a 3.3V Low Voltage CMOS (LVCMOS) interface connector that includes camera control, digital video output, analog video output, and camera synchronization signals.
6 Camera Interfacing The Tau CNV camera parameters are controlled and status monitored using serial communication via an LVDS parallel, USB, or Camera Link connection. Digital video data and triggering are also available over the LVDS parallel and Camera Link connection. Non-digital NTSC analog video is also available.
+12 VDC No Connection 6.1.2 Parallel Data Connector The Tau CNV camera (with LVDS parallel configuration) can provide 14-bit or 16-bit CMOS data with sync signals as well as analog video output simultaneously. Table 3: Parallel Interface Connector Pin Out...

A complete description of the Camera Link standard can be purchased from the AIA organization at http://www.machinevisiononline.org/store/category.cfm?category_id=76. The FLIR AIS Tau CNV camera provides a Frame Valid (FVAL) pulse which goes high during the reading out of the frame and goes low after reading out the complete frame.
The Trigger IO connector is a Hirose SR38-4R-3S(71) and is labeled “TRIG IN/OUT on the rear of the camera.

NOTE: For proper operation, external trigger falling edges must never occur at a rate faster than the minimum frame period (approximately 33ms). These trigger modes are fully described in the Tau CNV interface control document (ICD). Contact your local sales or technical support for details.
7.3 Lens Mounting and Back Focus Adjustment The FLIR AIS Tau CNV camera has two options for lens mounting: The M42/C-mount and the M42/F-mount. After mounting the lens into the C-mount lens adapter, the camera must be back focus adjusted and locked prior to use.
The Tau CNV operating temperature is specified as a case temperature range of -20°C to +50°C with degraded performance in the +35°C to +50°C The Tau CNV sensor mount is used to both mount the camera to the user’s assembly, and to conduct heat away from the camera electronics. The camera makes automatic and continuous adjustment to compensate for changes in case temperature;...
7 operating system using a standard PC serial COM port, USB port or a Camera Link compatible frame grabber which enables a serial COM port. With one of these connections cabled to the Tau CNV camera, the camera controller GUI can be used to control operating modes and gather status. Most of the user programmable functions that can be set and read by serial commands may also be set and read by using the Universal Camera Controller.
