We have 3 sensor technology candidates – global shutter, rolling shutter and EVB. This is the third post in How to Image Moving Objects post series where we compare these 3 technologies imaging the very same target with the same conditions

Our challenge to image a moving target continues and this time in our How to Image Moving Objects post series we explore how a camera rolling shutter works

We are not prophets! At one point or another in the design process we must assess if the system is going to perform as we wanted it to. In this post we explore one very important tool for this task – the Tolerance Analysis

Moving objects imaging has its inherent challenges. In this first post out of 3 posts series we explore how a camera global shutter works.

A head-to-head comparison between color and monochrome cameras with versions of the same sensor, to show specific differences between the two

Eventually, in visible color imaging we want the best image with the most vivid colors. In this post we do the final color balancing, having all the previous episodes’ methods into practice

Illumination sources differ in their spectral content. We explore in this post how we measure it, how it impacts our raw image and how white balance is one way to deal with its effects

In this post in the wonders of colors series we define a reliable method to measure the different colors and explore the spectrometry concept.

In this first post in the wonders of colors post series we establish that eventually our image is an image processing of an outcome of light, camera and viewing device

In this post in the Event-Based cameras series we explore an imaging application of a very interesting mechanical phenomenon – crack growth. The application will show the clear advantages of using neuromorphic cameras for these fast moving cases

The day-to-day optical tasks change when dealing with an event-based camera. Ever thought how to focus a static scene when there is not image if the scene is static? Read about focusing methods when using neuromorphic cameras

Event-Based cameras start to emerge here and there in the industry. In this first post in this post series we give an introduction to a different imaging technology that may become handy in many applications.

We already know that ghosts in optical systems exist, but how about real ghosts, images of objects that do not appear in the original FOV? This is the second of a two posts series about ghosts in imaging systems

What are ghosts in an imaging system? Why do we see them in our final images? This is the first of a two posts series about ghosts in imaging systems

The camera is the heart of an imaging system and as such the camera selection is a crucial engineering process. This post covers the main aspects of the process.

Requirements for an imaging system are always challenging. Did we cover everything? In this post we detail the important parameters and items that should appear in our Imaging System Requirements.

As we integrate lasers in many optical systems we must define the laser requirements properly to achieve the best fit laser unit. This post details the different parameters that should be considered when collecting these requirements.

This post covers the basics of optical aberrations, monochromatic and chromatic, in a down-to-earth explanation with hints to remember it

Demonstrating through examples how both Optics and Algo engineering together are a must for an optical system from the very beginning of a project
