Spherical Optics

By Lynn M. Savage, Features Editor

Individually, micro-optics are a few millimeters in diameter at best, but together these tiny lenses comprise a powerful link to future technologies that will affect everything from advanced computers to human health. Micro-optics permit the manipulation and management of light at a scale that allows photonic systems to more easily connect with electronics, which will help promote optoelectronic communication at faster speeds than have yet been achieved. They are an important technology for the development of improved laser beam shaping devices and optical fiber couplings, for example,...Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
    micro-optics
    Micro-optics refers to the design, fabrication, and application of optical components and systems at a microscale level. These components are miniaturized optical elements that manipulate light at a microscopic level, providing functionalities such as focusing, collimating, splitting, and shaping light beams. Micro-optics play a crucial role in various fields, including telecommunications, imaging systems, medical devices, sensors, and consumer electronics. Key points about micro-optics: ...
    optical coherence tomography
    Optical coherence tomography (OCT) is a non-invasive imaging technique used in medical and scientific fields to capture high-resolution, cross-sectional images of biological tissues. It provides detailed, real-time, and three-dimensional visualization of tissue structures at the micrometer scale. OCT is particularly valuable in ophthalmology, cardiology, dermatology, and various other medical specialties. Here are the key features and components of optical coherence tomography: Principle of...
