NOTE 1The pixel pitch in the 45 degree diagonal direction is not the same as in the vertical and horizontal directions. Therefore, the diagonal pixel pitch is used when applying this table to measurements in the diagonal directionsNOTE 2There are three planes for determination of the resolution in e.g. LP/mm. It can be in the object space, on the sensor plane or in the image with a given output magnification. In most cases the resolution on the sensor plane is the important one. To get the right value for this situation the image file should be scaled to the Sensor dimension in which case the pixel pitch on the sensor is equal to the pitch of pixels in the image file.

I’ve found my laser level to be a quick and easy way to get straight lines, without having to draw them. There are several different brands that basically do the same thing. The one shown is the one I have.

Unlike a light box or pencil guidelines, a laser level won’t help you keep your letter heights consistent, but if you’ve been doing calligraphy for a while and/or you aren’t that concerned about that (as with less formal calligraphy), it’s a great option.

Resolition is measured using edges, Siemens stars or other regular structures with aíncreasing frequencies. Units like LW/PH, LP/PH, or Cycles per pixel are independent of the sensor size and the pixel pitch. They just take the resulting image and its frequency content into account not caring about the size of each pixel. Dimensions like LP/mm, L/mm, or Cycles/mm require the knowledge about the sensor size / pixel pitch.The following table and explanation will be part of the upcoming revision of ISO 12233 and was created by Don Williams.

If you place your envelope or paper on top of some guidelines that extend out from each side, you can just line up the laser light with the guideline, and you will get a straight line, quickly and easily. (In these photos, I have just used the lines on my cutting mat! This mat is similar to, but not exactly the same one as mine.) You then just write on the line of light, just as you would a pencil line. (You can even eyeball it, without using any guidelines under the envelope, if you’re good at that.)
