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. Fairchild Imaging recommends mounting the camera using these holes to minimize sensor dark current[...]

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. Do you know the speed of the object that your camera will be inspecting? One additional point you want to keep in mind is your lighti[...]

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. Cable construction with shielded[...]

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. Fairchild Imaging supplies configuration files for each camera ty[...]

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. 3.3.1 Direct Trigger[...]

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 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. For 2K / 4KTDI LVDS cameras, the TDI [...]

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. Values written to RAM are implemented immediately. 3.9 How to Modify Gain & Offset Valu[...]

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. 3.10.1 STROBE STROBE is an internal pixel clock inside the camera (fixed at 25 MHz) data rate. To[...]

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. Sensor alignment is to the four M4 face mounting holes. The 2K and 4K TDI camera housings are equipped with four M4 mounting holes on the front and two M4 mounting holes on one side a[...]

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 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: hardware & software • Is the frame grabber plugged into the correct slot on the mother board? • Are all electrical connections secure? • Chec[...]

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. Data Clocking/Output Signals Verify the presence of all data clocking and output [...]

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. If the object you are inspecting [...]
