A Deeper Dive into the Illumination “W”

You probably recall the illumination “W” that is a foundational concept for machine vision illumination design (see Figure 1). You also probably recall that the illumination “W” is based on a flat, perpendicular, specular or mirror-like surface. Further examination of the “W” reveals characteristics that can further help with your design of lighting in implementing bright field or dark field lighting.

C-47 aka clothespin

The C47

The C47 is incredibly cheap and extremely useful, as is a wide array of clamps, in the machine vision laboratory.  The C47 appears identical to an ordinary wooden clothespin.  (I’ll let you in on a secret:  they’re the same.)

A Data What?

Humpty-Dumpty told Alice, “When I use a word, it means just what I choose it to mean – neither more nor less.”

In the new field of data science, the practitioners are known as data scientists.  This appears quite consistent.
