PRELIMINARY SECTION 1 Introduction to the CAM/CCD-2KLV.TDI and CAM/CCD-4KLV.TDI High Performance TDI Line Scan Camera 1.1 Camera Highlights Description The Osprey TDI camera series is an ultra-sensitive camera design for use in line scan applications that demand high performance under low light conditions.
PRELIMINARY Programmability Simple menu-based configuration for selection of gain, offset operational control, and diagnostics. • LVDS camera-PC communications with Fairchild-supplied user GUI.
PRELIMINARY Notes: DN = Digital Numbers, also known as “levels” (0 – 255 for 8-bit systems, 0 – 4095 for 12-bit systems). All measurements taken with camera operating in 96 stage mode. All measurements exclude the last pixel of OS 1 and the first pixel of OS4.

PRELIMINARY 1.8 Thermal Considerations The Osprey camera series has been thermally designed to separate the camera electronics from the image sensor. The sensor temperature is thermally linked near the four M4 mounting holes on the face of the camera.
PRELIMINARY SECTION 2 Camera Hardware Interface 2.1 Installation Overview Before you integrate your camera into your system you should first determine some basic operating parameters such as what resolution you need.

PRELIMINARY 2.3 Power Supply The camera uses a single voltage input, normally set to 12 volts @ 0.7 Amps typ., supplied through a Hirose connector. The supply must support a 850mA current surge for 100ms for proper camera operation. Ripple and noise is required to be < 50 mV RMS for best camera noise performance.
PRELIMINARY SECTION 3 Camera Control 3.1 Quick Start with LVDS Interface Follow your frame grabber manufacturer’s instructions when inserting the frame grabber card into your PC. Be sure that you install the correct configuration software that matches the camera that you are using.
PRELIMINARY 3.3 Providing External Triggering There are two ways to provide external triggering to the 2K & 4K TDI LVDS cameras: • Directly send the external trigger to the camera’s DB15 connector as mentioned earlier. • Provide an external trigger to the frame grabber and it will send the EXSYNC signal to the camera.
PRELIMINARY 3.2.3 TTL Trigger Source If the external trigger source is a TTL level, the signal needs to be conv erted to a LVDS signal before sending it to the camera.
PRELIMINARY EXSYN C - EXSYN C + 3.5 Frame Mode Framing mode is an excellent tool for mechanical and optical aligning of the camera to the target. Frame mode is available in master mode only and the line rate is fixed at 23.

PRELIMINARY 3.7 TDI Length Selection TDI length selection for the 2K/4KTDI LVDS camera can be selected using the combination of TDISEL0 and TDISEL1 input signal into the DB15 control connector. The TDISEL0 and TDISEL1 are LVDS level signals. They are typically wired to the user control I/O of the frame grabber.
PRELIMINARY 3.8 Gain and Offset Calibration Gain and offset calibration are supported with use of the "FI LVDS Camera Control" graphic user interface (GUI). Note: When saving directly into ROM, stored values are not applied until after power cycle.
PRELIMINARY 3.10 Data Bus The 2K and 4K TDI cameras have 4 channels of 8-bit digital data in RS-644 (LVDS) format. See Reference B of this manual for detailed information on RS644. Both 2K and 4K TDI cameras output the clocking signals STROBE and LVAL.
PRELIMINARY SECTION 4 Mechanical and Optical Considerations 4.1 Camera Dimensions and Mounting The 2K and 4K TDI camera housings are manufactured with high precision.
PRELIMINARY 4.2 Lenses The 2K and 4K TDI cameras as shipped from the factory accept M58 optical components with M58 threads. The 4K TDI camera only acc epts M58 lens types.
PRELIMINARY 4.3 Mechanical Drawing of Optional Camera Face Mounting “L” Bracket Contact your Fairchild Imaging representative for more details. 4.4 Lenses Fairchild Imaging does not supply lenses. An ex ample lens setup is detailed in Section 4.2 above.
PRELIMINARY 4.5 Positioning Accuracy of th e Sensor Chip in the Camera Position accuracy of the sensor chip in th e horizontal and vertical dir ection is + 2 mils. Rotational positioning accuracy is as shown. Reference position is the center-line of the four M4 mounting holes of the camera housing.
PRELIMINARY 4.8 Lens Modeling Several camera companies have included this and like information in their manuals. For reference material it is very useful. The focal point is the point at which the image of an infinitely distant object is bro ught to focus.
PRELIMINARY SECTION 5 Handling Instructions 5.1 Electrostatic Discharge The Fairchild Imaging Osprey camera uses TDI technology in a CCD base, and as all such devices, has some limited inherent susceptibility to electrostatic discharge (ESD). All reasonable and customary design steps have been taken to provide ESD protection circuitry.
PRELIMINARY SECTION 6 Troubleshooting 6.1 Check Simple Things First When troubleshooting, you want to start the process with the obvious components contained within your system: • Computer system: h.
PRELIMINARY Everything Seems to be Working, But No Image Remove the cover from your PC and reset all the cards into the mother board. Sometimes when you move your PC, cards inside the PC work themselves loose. Don’t forget to check for optical path obscuration also.
PRELIMINARY Look at your light source. Keep in mind that it is better on the si de of too much light rather than too little. Exce ss light allows internal ga in reduction in the camera which, in turn, improves camera dynamic r ange. Also, if your light source is AC instead of DC this will make the image look noisy.
PRELIMINARY SECTION 7 Product Support If, after troubleshooting your camera, you are still having problems, collect the following data about your application and call Fairchild Imaging Custo mer Support.
PRELIMINARY REFERENCE A Providing External Trigger Using PCI-1424 Frame Grabber 1. Modify the frame grabber cable with the following connection: Refer to the NI PCI-1424 TO 4KTDI LVDS CABLE PIN CONFIG.
PRELIMINARY REFERENCE B Introduction to LVDS National Semiconductor first introduced LVDS as a standard in 1994. National recognized that the demand for bandwidth was increasing at an exponential rate while users also desired low power dissipation. This exceeded the speed capabilities of RS-422 and RS- 485 differential transmission standards.
