Focal distance is a different concept. It refers to the distance between the subject of your image and the sensor or film plane when the lens is focused on a subject. Changing the focal distance affects how much of your scene is in focus from front to back. Lenses also have a minimum f...

To develop and model an optical system for machine vision, the first step is to define the requirements. Often the starting point includes requirements for a specific focal plane to be used in the imaging system, with a certain sensitivity. This has implications on the illumination system, inclu...
What is focal vision?The Human Visual SystemNormally, people don't give much thought to how their vision works. Therefore, it may come as a surprise that the human visual system actually is made up of two main parts. Focal vision is one of those main parts, and it plays an individual ...
The photons that reach the front of the sensor are collected by the lens and focused onto a focal plane at the back of the sensor body. The focal plane is a collection of physical cells, such as a CCD array, that are sensitive to the photons. These are the physical devices that measur...
