Optics for Machine Vision
For a long time, the nature of light baffled scientists. Many machine vision practitioners have misunderstandings about the nature of light that make it difficult to understand how light is working for them. This video explains, in plain language, what light is and what light is not.
What is Light?
Part 1 of 9 (6:58)For a long time, the nature of light baffled scientists. Many machine vision practitioners have misunderstandings about the nature of light that make it difficult to understand how light is working for them. This video explains, in plain language, what light is and what light is not.

There are three properties of light energy that are critical to understanding the behavior of light: spectrum, coherence, and polarization. This video explains each of these properties.
Properties of Light
Part 2 of 9 (10:35)There are three properties of light energy that are critical to understanding the behavior of light: spectrum, coherence, and polarization. This video explains each of these properties.

When light interacts with a material, three things can happen: reflection, absorption, and transmission. Each of these three effects may be different depending on the material. This video explains the three actions and the ways they might vary with material.
Light in Action
Part 3 of 9 (11:05)When light interacts with a material, three things can happen: reflection, absorption, and transmission. Each of these three effects may be different depending on the material. This video explains the three actions and the ways they might vary with material.

This video goes deeper into reflection, absorption, and transmission to explain light behaviors that may otherwise baffle the machine vision practitioner. The video also gives more details about the polarization of light. Finally, the video explains diffraction and interference that have important impacts on light and how it behaves in machine vision systems.

Color as a property of light relates to its wavelength. As something that humans and machine vision sense, it’s a bit different. This video explores how humans and machine vision cameras sense color and two different ways that color can be represented.
How Color is Sensed
Part 5 of 9 (15:09)Color as a property of light relates to its wavelength. As something that humans and machine vision sense, it’s a bit different. This video explores how humans and machine vision cameras sense color and two different ways that color can be represented.

This video describes the different ways that light is measured as well as the three different systems of measurement. There is some confusion and misunderstanding in how light is measured and which measurement is appropriate for a particular circumstance. This overview helps clear the confusion and minunderstandings.
The Measurement of Light
Part 6 of 9 (9:15)This video describes the different ways that light is measured as well as the three different systems of measurement. There is some confusion and misunderstanding in how light is measured and which measurement is appropriate for a particular circumstance. This overview helps clear the confusion and minunderstandings.

This video describes the basics of how images are formed by lenses. The discussion starts with the pinhole as an imaging device and then introduces the concepts of the lens. It introduces the basic lens equations that are important in machine vision work.
How Images are Formed
Part 7 of 9 (9:50)This video describes the basics of how images are formed by lenses. The discussion starts with the pinhole as an imaging device and then introduces the concepts of the lens. It introduces the basic lens equations that are important in machine vision work.
