Work experience and proven skills in ray tracing and optimization are important for good optical engineers, so ask potential candidates for examples of their work in these areas before you hire them.
Stray light is a major limiting factor in many imaging systems. When stray light enters the system, it degrades the signal-to-noise ratio or contrast ratio, making it more difficult to obtain accurate images. There are many ways to prevent stray light in an optical system. In this article we will review five.
In a previous article we talked about Aviation Light Optics. and discussed a runway light system called Precision Approach Path Indicator (PAPI). Now we would like to go more in detail into PAPI design and describe their design requirements. The PAPI system...
This will be the last entry in our series of optical instrumentation for optometry. If this is the first article that you are seeing, I would suggest that you take a look at our previous articles about Ophthalmoscope Design, Keratometer Design, and Retinoscopy. This...
In the next couple of articles, we will talk about the different instrumentation used by ophthalmologists and optometrists. As you can imagine, there are many restrictions when designing an optical instrument that will be used in a patient. It matters whether the...
Projection systems are one of the most common consumer optical devices (probably second to photographic systems). They allow us to view images on a screen (usually) by magnifying and projecting them at distances from a few centimeters to several meters away...
Introduction A 4F optical system is a system architecture that uses Fourier Optics. In this article, we will explain why we need them and how to design a simple 4f correlator. We will leave out most of the mathematical derivations, but if you are interested...
Introduction Optical relays, an integral component of various optical systems, play a crucial role when the user's proximity to the observed object is limited or when specific image transformations are required. A prevalent example of this is found in relay lenses,...
Opto mechanical design overview and definitions In an opto-mechanical design we work on the positioning of optical elements such as lenses, filters, beamsplitters, reflectors, and diffractive elements in mechanical structures that will allow the optical...
A designer of an IR optical system needs to account for key specifications that greatly impact the complexity of the device construction and its production cost. The most important requirements are described below. The maximum achievable theoretical resolution in...
Hello from Optics for Hire, where the topic of 3-D display has been coming up even more than usual. At the moment, the clouds over Arlington are trying to figure out how much snow to deposit on Mass Ave. Feels like the right mood to share a few of the things...
