As previously, a slider is provided for adjustment to ensure that the areas sampled are within the targets. Adjust as necessary for the available Spectralon diffuse reflectance standards. Note that this should not be necessary if the position of the targets has not moved significantly between frames and the alignment procedure was carried out in the previous tab. 25) Scroll right to column Q. This extracts the X, Y and Z values from the 99% Spectralon reflectance standard from the matrix generated for the VIL image (Q38, Figure 3-88).The corresponding values for the IRR image (Q39, Figure 3-88) are automatically carried over from the x tab (as determined in the workflow for the correction of IRR images). 26) Images of the mathematically reconstructed ambient stray radiation present (Q3, Figure 3-88) are generated using the above values, as described in Chapter 1. 27) These are subtracted from the corresponding VIL images. The resultant images can be observed at Q47. To view the images, double-click on the “targets” or “object” thumbnails (Figure 3-89). Version No. 1.0 175 Date : 14/10/2013
