Spyder 3 GigE User’s Manual 45 5.1 Electrostatic Discharge and the CCD Sensor Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge (ESD). Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity.
Spyder 3 GigE User Manual 46 5.3 Cleaning the Sensor Window 1. Use compressed air to blow off loose particles. This step alone is usually sufficient to clean the sensor window. 2. If further cleaning is required, use a lens wiper moistened with alcohol or acetone. 3. We recommend using lint-free ESD-safe cloth wipers that do not contain particles that can scratch the window. The Anticon Gold 9”x 9” wiper made by Milliken is both ESD safe and suitable for class 100 environments.

Spyder 3 GigE User Manual 66 A2 Data Processing A2.1 Setting a Region of Interest (ROI) Purpose: Sets the pixel range used to collect the end-of-line statistics and sets the region of pixels used in the ccg, cao, gl, gla, ccf, and ccp commands. In most applications, the field of view exceeds the required object size and these extraneous areas should be ignored. It is recommended that you set the region of interest a few pixels inside the actual useable image.
Spyder 3 GigE User’s Manual 67 A2.2 Analog and Digital Signal Processing Chain 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.
Spyder 3 GigE User Manual 68 To optimize camera performance, digital signal processing should be completed after any analog adjustments. 1. Fixed pattern noise (FPN) calibration (calculated using the ccf command) is used to subtract away individual pixel dark current. 2. The digital offset (sdo command) enables the subtraction of the “artificial” A/D offset (the analog offset) so that application of the PRNU coefficient doesn’t result in artifacts at low light levels due to the offset value.
Spyder 3 GigE User’s Manual 69 Purpose: Instead of manually setting the analog gain to a specific value, the camera can determine appropriate gain values. This command calculates and sets the analog gain according to the algorithm determined by the first parameter. Syntax: ccg i t i Syntax Elements: i Calibration algorithm to use. 1 = This algorithm adjusts analog gain so that 8% to 13% of tap region of interest (ROI) pixels are above the specified target value.
Spyder 3 GigE User Manual 70 Purpose: 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. Syntax: sao t i Syntax Elements: t Tap selection. Use 0 for all taps or 1 to 2 for individual tap selection if you are using the two tap model.
Spyder 3 GigE User’s Manual 71 Calibrating the Camera to Remove Non-Uniformity (Flat Field Correction) Flat Field Correction Overview Note: The QuickCam software that ships with the Spyder 3 GigE camera has a flat field correction wizard. For easy flat field correction, use the wizard located on the Calibration tab. This camera has the ability to calculate correction coefficients in order to remove nonuniformity in the image.
Spyder 3 GigE User Manual 72 For best results, ensure that: • 50 or 60 Hz ambient light flicker is sufficiently low not to affect camera performance and calibration results.
Spyder 3 GigE User’s Manual 73 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.
Spyder 3 GigE User Manual 74 Digital Signal Processing To optimize camera performance, digital signal processing should be completed after any analog adjustments. FPN Correction Performing FPN Correction Syntax: Performs FPN correction and eliminates FPN noise by subtracting away individual pixel dark current. Syntax: ccf Notes: • Perform all analog and digital adjustments before performing FPN correction. • Perform FPN correction before PRNU correction.
Spyder 3 GigE User’s Manual 75 Setting Digital Offset Purpose: Sets the digital offset. Digital offset is set to zero when you perform FPN correction (ccf command). If you are unable to perform FPN correction, you can partially remove FPN by adjusting the digital offset. 87H Syntax: sdo t i Syntax Elements: t Tap selection. Allowable range is 1 to 2 depending on camera model, or 0 for all taps.
Spyder 3 GigE User Manual 76 PRNU Correction Performing PRNU to a user entered value Purpose: 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 ssb command to be set to 0 (no background subtraction) and the ssg command to 4096 (unity digital gain).
Spyder 3 GigE User’s Manual 77 for use only when FPN is negligible and FPN coefficients are set to zero. Since this algorithm adjusts the analog gain, it also affects FPN. If FPN is calibrated prior to running this algorithm, FPN will be observable in dark conditions and an incorrect FPN value will be used during PRNU calibration resulting in 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.
