In the last month, I have had the need to travel several times by airplane. So, after several hours enjoying $15 sodas, and $30 hamburgers at the airport gates, I started paying more attention to the different illumination systems that are being used in the aviation...
光学准直仪也称为非成像浓度器是可以从源收集和投射光的光学组件。常见的例子包括集中太阳光并投射其加热表面或将其引导到太阳能电池板的太阳能收集器。
这将是我们用于验光的光学仪器系列中的最后一个条目。如果这是您看到的第一篇文章，我建议您查看我们以前有关眼镜设计，角化仪设计和视网膜镜检查的文章。这个...
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...
This is our last entry on our scanning mirrors series. In this article, we will talk about the use of scanning mirrors when working with welding environments. As you can imagine, not only do the optical requirements differ when compared to those of a scanning...
This is our third installment of a four-series blogs about steering mirrors. We have talked previously about steering mirrors in laser markings and steering mirrors in OCT systems. This week, we will talk about the steering mirror requirements for those in LIDAR...
Introduction In previous entries, we have talked about the design of scanning microscopes, infinity corrected microscopes, confocal microscope design, and Koehler illumination systems-a common illumination system in microscopes. The most essential microscope element...
Endoscopes are medical devices designed to collect the smallest images from inside the human body. Endoscopes can be divided into two categories: rigid endoscopes, in which relay lenses are stacked together generally creating a high-quality image, and flexible...
When I was a young undergrad engineering student, I always found optics to be a very confusing subject. It was not only the equations, but what it looked like hundreds of different definitions involved in even the simplest of optical systems. Some concepts, like...
先前的帖子已经审查了光束均质化以及斑点尺寸和光束角之间的差异的不同技术。这篇文章将审查使用Powell镜头进行光束塑形的方法。鲍威尔镜头是通过...创建直线激光线的镜头
玻璃的选择是光学设计过程中的基本部分。IR和热光学材料尤其如此。在本文中，我们将讨论氟化钙（CAF2），这是一种有趣的玻璃，具有广泛的应用。
梁拆分器是光学系统中的基本元素。从本质上讲，光束拆分器是用于将单个光源（通常是激光器）分为两个单独的光束的光学组件。更常见的光束拆分器（您在大多数...中都可以找到的那种...
When designing any optical system, an optical engineer needs to consider how illumination will be used: specifically, how the illumination could affect the way the image is created. If not carefully designed, some illumination systems may create a kind of...
在许多镜头设计配置中，最常见的镜头光学布局之一是Tessar镜头。这种布局是由保罗·鲁道夫（Paul Rudolph）于1902年创建的，用于摄影镜片。在电影摄影的黄金时代，...
有不同的方法来计算激光束的质量。通常，我们希望激光束尽可能接近理论高斯梁。那么问题是我们如何测量光束的轮廓，以及如何将其与...进行比较。
共聚焦显微镜是一种非常流行的高质量图像技术。由于样品的制备相对简单，在使用组织或生物样本时非常有用。共聚焦显微镜是传统的显微镜。而在...
任何通过酒店房间窥视孔达到顶峰的人都使用了鱼眼镜头。通常，鱼眼镜镜的焦距非常短（35毫米大小的图像传感器小于15mm），但视野很大（FOV）。后者可以和...
抛物线镜是用于收集或分配能量的光学系统。他们有各种各样的应用，从用于水加热系统的太阳能收集器到显微镜和望远镜以及日常手电筒。最常见的方法...
In an achromatic lens design, we optimize such that two wavelengths, usually red (590nm) and blue (495nm), focus on the same image plane. This is done to reduce chromatic aberration. In this article, we’ll talk about a similar design type called an...
A previous post discussed underwater optical design. This week, we will review the diametrical opposite application - free-space optical communication (FSO). As with underwater optical design, one of the challenges facing FSO is the optical signal propagation...
