Spyder3 GigE Vision User’s Manual 17 2.2 Mounting DALSA DALSA recommends that you allow the heat generated by the camera to move away from the camera. One way to do this is by mounting the camera correctly, as shown: 2.3 Optical Interface Illumination The amount and wavelengths of light required to capture useful images depend on the particular application.
Spyder3 GigE Vision User Manual 18 • LED light sources are relatively inexpensive, provide a uniform field, and longer life span compared to other light sources. However, they also require a camera with excellent sensitivity, such as the Spyder3 GEV camera. • Halogen light sources generally provide very little blue relative to infrared light (IR). • Fiber-optic light distribution systems generally transmit very little blue relative to IR.

Spyder3 GigE Vision User Manual 34 5.3 First Power Up Camera Settings When the camera is powered up for the first time, it operates using the following factory settings: • High sensitivity mode. • Forward CCD shift direction. • No binning. • Exposure mode 7 (Programmable line rate & max exposure time). • 5000 Hz line rate. • Factory calibrated analog gain and offset. • Analog gain enabled (1k and 2k use).
Spyder3 GigE Vision User’s Manual 35 Sensor Shift Direction When in high sensitivity mode, you can select either forward or reverse CCD shift direction. Selectable direction accommodates object direction change on a web and allows you to mount the camera “upside down”.
Spyder3 GigE Vision User Manual 36 5.5 Timing: Exposure and Synchronization Image exposures are initiated by an event. The trigger event is either the camera's programmable internal clock used in free running mode, an external input used for synchronizing exposures to external triggers, or a programmed function call message by the controlling computer. These triggering modes are described below.

Spyder3 GigE Vision User Manual 38 Exposure Mode, Readout Mode, Line Rate and Exposure Time Overview You have a choice of operating in one of seven modes. The camera’s line rate (synchronization) can be generated internally through the software command AcquisitionLineRateAbs or set externally with an EXSYNC signal, depending on your mode of operation. To select how you want the camera’s line rate to be generated: 1. You must first set the camera mode using the DALSAExposureMode command. 2.
Spyder3 GigE Vision User’s Manual 39 Exposure Modes in Detail Mode 2: Internally Programmable Line Rate and Exposure Time (Factory Setting) Mode 2 operates at a maximum line rate and exposure time. • When setting the line rate (using the AcquisitionLineRateAbs command), exposure time will be reduced, if necessary, to accommodate the new line rate.
Spyder3 GigE Vision User Manual 40 Mode 4: Smart EXSYNC, External Line Rate and Exposure Time In this mode, EXSYNC sets both the line period and the exposure time. The rising edge of EXSYNC marks the beginning of the exposure and the falling edge initiates readout. Example 3: Trigger Period is Repetitive and Greater than Read Out Time.
Spyder3 GigE Vision User’s Manual 41 Mode 7: Internally Programmable Line Rate, Maximum Exposure Time In this mode, the line rate is set internally with a maximum exposure time.

Setting the GPIO Output Signal Sets the signal type for the selected output. GPIOSelector Output to set. Port0 = Output 0, pin 11 (TTL) or 11 and 12 (LVDS) Port1 = Output 1, pin 13 (TTL) or 13 and 14 (LVDS) Port2 = Output 2, pin 15 (TTL) or 15 and 10 (LVDS) Port3 = Output 3, pin 9 (TTL) GPIOOutput Signal type.
Spyder3 GigE Vision User Manual 44 5.7 Data Processing Processing Chain Overview and Description The following diagram shows a simplified block diagram of the camera’s analog and digital processing chain. The analog processing chain begins with an analog gain adjustment, followed by an analog offset adjustment. These adjustments are applied to the video analog signal prior to its digitization by an A/D converter.
Spyder3 GigE Vision User’s Manual 45 at only 50% of the DN. An analog gain of 6 dB (2x) will ensure full use of the dynamic range of the A/D converter. Of course the noise is also increased. Note: To maintain valid LUT calibration, do not use the GainAbs command with the 4k model. Instead, use the DigitalGainRaw command. 2. The analog offset (BlackLevelRaw command) or black level is an “artificial” offset introduced into the video path to ensure that the A/D is functioning properly.
Spyder3 GigE Vision User Manual 46 Sets the camera’s analog gain value. Analog gain is multiplied by the analog signal to increase the signal strength before the A/D conversion. It is used to take advantage of the full dynamic range of the A/D converter. GainSelector Tap selection: All or Tap1 to Tap2 for individual tap selection. GainAbs Gain value in a range from –10 to +10dB. • Not available on the 4k model.
Spyder3 GigE Vision User’s Manual 47 Setting Analog Offset Sets the analog offset. The analog offset should be set so that it is at least 3 times the rms noise value at the current gain. DALSA configures the analog offset for the noise at the maximum specified gain and as a result you should not need to adjust the analog offset. BlackLevelSelector Tap selection: All, Tap1, or Tap2 for individual tap selection if you are using the two tap model.
Spyder3 GigE Vision User Manual 48 The white light calibration is performed next to determine the multiplication factors required to bring each pixel to the required value (target) for flat, white output. Video output is set slightly above the brightest pixel (depending on offset subtracted). Flat Field Correction Restrictions It is important to do the FPN correction first. Results of the FPN correction are used in the PRNU procedure.
Spyder3 GigE Vision User’s Manual 49 Set up the camera operating environment (i.e. line rate, exposure, offset, gain, etc.) Set the calibration sample size using the command css. It is recommended that you use the default setting. Set the region of interest to include all of the image’s pixels of importance using the command roi x1 y1 x2 y2. You can use the default if you want to calibrate all pixels. Perform FPN calculation Perform PRNU calculation 1. Stop all light from entering the camera.
Spyder3 GigE Vision User Manual 50 Digital Signal Processing To optimize camera performance, digital signal processing should be completed after any analog adjustments. FPN Correction Performing FPN Correction Performs FPN correction and eliminates FPN noise by subtracting away individual pixel dark current. CorrectionCalibrateFPN • Perform all analog and digital adjustments before performing FPN correction. • Perform FPN correction before PRNU correction.
Spyder3 GigE Vision User’s Manual 51 Performing PRNU to a user entered value Performs PRNU calibration to user entered value and eliminates the difference in responsivity between the most and least sensitive pixel creating a uniform response to light. Using this command, you must provide a calibration target. Executing these algorithms causes the SubtractBackgroundRaw command to be set to 0 (no background subtraction) and the DigitalGainRaw command to 4096 (unity digital gain).
Spyder3 GigE Vision User Manual 52 incorrect PRNU coefficients. This algorithm is more robust and repeatable than algorithm 1 because it uses an average pixel value rather than a number above target. However, this algorithm is slower. i Peak target value in a range from 1024 to 4055DN. The target value must be greater than the current peak output value. Notes: • Perform all analog adjustments before calibrating PRNU.

Related Commands: CorrectionCalibrateFPN, CalculatePRNUAlgorithmTargetValue CalculatePRNUAlgorithmTargetValue • Perform all analog adjustments before calibrating PRNU. • This command performs the same function as the CorrectionCalibratePRNU command but forces you to enter a target value. • Calibrate FPN before calibrating PRNU.
Spyder3 GigE Vision User Manual 54 Setting Digital System Gain Improves signal output swing after a background subtract. When subtracting a digital value from the digital video signal, using the SubtractBackgroundRaw command, the output can no longer reach its maximum.
