Page 23: Phosphorescence
Phosphorescence ® The VSC 90 uses a source of UV-A light, 365 nm, to excite certain dyes or inks that will continue to emit radiation in the form of light for a short time once the source of excitement is no longer active. Fluorescence describes an ink that emits a longer wavelength of light during excitation, whereas phosphorescence describes the ability of an ink to continue to emit this light after the source of excitation is switched off. Capture of this phosphorescence relies on a frame delay, the time between t he source of excitation being switched off, and image capture. This frame delay can be determined by the user within the software. See: "Phosphorescence" on page 30. Nominal w avelength (nm) Colour Bandwidth ( 10%) Peak Ultraviolet (UV) 350 - 380... -
Page 24: Optical Filters
Optical Filters ® ® The VSC 90 contains 13 individual filters that are mounted on a wheel and controlled by the VSC software. Filter Types There are three filter types available, along with different light sources and illumination modes available ® within the VSC 90, allow for the document examiner to select precise wavelength ranges to view security features, or to determine the authenticity and integrity of a questioned document. Longpass Filter A longpass filter will block the shorter wavelengths and allow the longer w avelengths of light to transmit through the filter. Bandpass Filter A bandpass filter will block some of the shorter wavelengths and some of the longer wavelengths, allowing mid-range wavelengths of light to transmit through the filter. Shortpass Filter A shortpass filter will block the longer wavelengths and allow the shorter wavelengths of light to transmit through the filter. -

Page 37: Extended Camera Settings
Iris The iris controls how much light is taken in by the camera and influences the depth of field, also referred to as F-Stop. The depth of field denotes the distance at which the image is still in sharp focus. A smaller iris will result in a darker image and a deeper depth of field. A larger iris will result in a brighter image and a shorter depth of field. Auto Iris When selected, auto iris allows the software to adjust the iris and therefore the amount of light taken in by the camera. Focus The focus defines the clarity of an image and determines which areas of an image are sharp. Auto Focus When selected, auto focus allows the software to focus the camera on the object ® within the VSC Spot Focus Allows for the software to control the focus of the camera onto a single spot. Exposure Allows the user to override automatic exposure adjustments to make the image Compensation brighter or darker. Red Gain The gain determines the balance of light, dark and background noise within an image. A higher gain will result in a lighter image but increase the background noise. A lower gain will result in a dark image with less background noise. Use the slider to increase or decrease red gain. Blue Gain The gain determines the balance of light, dark and background noise within an image. A higher gain will result in a lighter image but increase the background noise. A lower gain will result in a dark image with less background noise. Use the slider to increase or decrease blue gain. Average Frames Each pixel in corresponding positions of multiple frames are averaged to create a ... - Page 38 Aperture The aperture is the hole created and controlled by the iris that allows the light to enter the camera to determine the depth of field. The depth of field denotes the distance at which the image is still in sharp focus. A lower aperture will result in a darker image and a deeper depth of field. A higher aperture will result in a brighter image and a shorter depth of field. Chroma Chroma refers to the purity of a colour, and chroma suppression is similar to Suppression saturation control. A hue with high chroma has no black, white or grey added to it. The higher the chroma suppression, the more black, white or grey is added to reduce the saturation of colours with a high chroma. Using chroma suppression will selectively desaturate specific high chroma colours, leaving other colours unaffected. It is used to remove false colours that may be visible on the edges of lines. Colour Gain Colour gain controls the intensity of colours within an image. Increasing colour gain will make colours appear more vibrant whereas decreasing colour gain will reduce the intensity of colours. Adjusting the colour gain will equally affect all colours within an image to increase or reduce colour intensity. Defogging Apply a defogging algorithm to reduce the effects of haze, smog, or other particles in the air that scatter and attenuate light to enhance the clarity of a captured image. The hue denotes the overall colour tint of an image. Noise Noise is defined as random and unwanted variations in brightness or colour that can Reduction make an image appear grainy, usually when an image is taken in low-light. Noise reduction involves the application of a digital filter that helps to reduce this noise and improve image clarity. Backlight This allows for the reduction of the effects of a strong backlight, or to increase light Compensation exposure for darkened areas, to improve the overall exposure of the image. High ...

Page 43: Mrz (Machine Readable Zones)
MRZ (Machine Readable Zones) Used to read MRZs within identity documents to determine if it conforms to ICAO (International Civil Aviation Organization) standards. Expected information is compared with the optical information obtained from the MRZ. The software reports errors on-screen and provides diagnostic tools to help users determine genuine nonconformity. Matches will be flagged with a green tick, and any issues will flag with a red cross. The validation process uses the standards specified in the ICAO document 9303 for Machine Readable Travel Documents. MRZ controls "Retry MRZ" will prompt reading of the MRZ after a failed attempt. "Save" will open a dialog box for the MRZ information to be saved to a specified location. "Edit MRZ" allows for the editing of any misread MRZ's. A window will open where the MRZ can be edited: Select an area with the mouse and use the keyboard to correct any misreads. ... - Page 44 "Default" returns the MRZ to the optical MRZ. "Test" will compare the MRZ to the ICAO standards. "Save" allows the MRZ to be saved. "Cancel" will return to the previous screen without editing the MRZ. "Read EChip" will prompt any connected E-chip readers to obtain the E-chip data for comparison with the optical MRZ. "Save PDF" will save the MRZ data as a PDF file. Select the save destination as required. "LS++" will open the LetterScreen++ controls: This will allow for the selection of the LetterScreen++ area by clicking and dragging the cursor from top-left to bottom-right and ensuring the entire image is inside the red box. Select the "LS++" button. Changing the colour table using the drop-down list allows for the selection of the pigment colour used in the LetterScreen feature. This can improve the capability of the software to detect the LetterScreen++ feature. However, RGB is the optimum setting and this should rarely need changing. "Pattern found" will display a green tick if positive, and a red cross if negative. "Save" will allow the LetterScreen++ to be saved. "Save PDF" will save the LetterScreen++ data into an individual PDF report. "Add to Macro" will add the LetterScreen++ function to a Macro, see: "Macros" on page 55. "Add to Macro" will allow MRZ reading to be added to a macro. See: "Macros" on page 55. "Image" will allow for the capture of an image of the MRZ.
