Seeing the Brain’s Electrical Activity

Neurons in the brain communicate via rapid electrical impulses that allow the brain to coordinate behavior, sensation, thoughts, and emotion. Scientists who want to study this electrical activity usually...

Rethinking FPGAs for Smart Cameras

The term “smart camera” has been used for decades, but there has been little agreement on the actual definition. This article will use the term “smart” as the Merriam Webster dictionary defines it: the...

Taking It to the Streets: Designing Streetlamp Optical Components

The task of creating a streetlamp optical system has changed over the last 20 years and due to this change, so has optical design software. Let’s compare the task of designing...

Lens-Free Fluorescent Microscope

Rice engineers have developed a wide-field microscope thinner than a credit card, small enough to sit on a fingertip and capable of micrometer resolution over a volume of several cubic millimeters.

Bringing Multispectral Imaging to Industrial Applications

A mere 20 years ago, machine vision system designers did all they could to avoid color imaging applications due to higher costs and greater system and software complexity. But as...
