Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) is a non-invasive medical imaging technique that uses light to capture high-resolution, cross-sectional images of biological tissues. OCT technology is based on the principle of low-coherence interferometry. A laser source emits a light wave which is divided into two light beams by a beamsplitter: one beam (i.e., the optical beam) is […]

Image Recovery or Image Reconstruction of an Imaging System

Blurring is a significant source of image degradation in an imperfect imaging system. The optical system’s point spread function (PSF) describes the measure of blur in a given imaging system and is often used in image reconstruction or image recovery algorithms. Below in example of using inverse PSF to eliminate the barcode image degradation. Barcodes are […]

How to Read an Optical Drawing

An optical drawing is a detailed plan that allows us to manufacture optical components according to a design and given specifications. When optical designers and engineers come up with a design, they condense it in an optical drawing that can be understood by manufacturers anywhere.  ISO 10110 is the most popular standard for optical drawing. […]

Infrared (IR) Lenses

An IR lens is an optical lens designed to collimate, focus, or collect infrared light. At Avantier Inc., we produce high performance IR Optics such as IR lenses for use with near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MIR), and long-wave infrared (LWIR) spectra. These Infrared lenses can be customized for specific areas of the […]

Identifying Resolution of Imaging Systems

Identifying Resolution of Imaging Systems Resolution is a measurement of an imaging system’s ability to resolve the object which is be imaged. Test targets are typically tools that are used to check the resolution of an imaging system. The most popular targets consist of “groups” of 6 “elements” and each element consists of three horizontal […]

LiDAR in Autonomous Vehicles

Today’s advanced driver assistance systems take advantage of AI-spiked cameras and radar or sonar systems, but most manufacturers have been waiting for advances in machine vision technology to go one step further into autonomous self-driving cars. Today, that technology is ready to roll out. We call it LiDAR: Light detection and ranging.  LIDAR in autonomous […]

Peak to Valley and Root Mean Square in Optics

How Peak to Valley (PV) and Root Mean Square (RMS) Affect the Quality of Your Optic Just how smooth is the surface of your optic? Qualitative descriptions are of limited value, and often you’ll want to put a number to it. Two ways of quantifying deviations from an ideal optical surface are peak-to-valley (PV) and […]

Introduction to Microscopes and Objective Lenses

A microscope is an optical device designed to magnify the image of an object, enabling details indiscernible to the human eye to be differentiated. A microscope may project the image onto the human eye or onto a camera or video device.  Historically microscopes were simple devices composed of two elements. Like a magnifying glass today, […]

Lossless Image Compression Example

For storage and transmission of large image files it is desirable to reduce the file size. For consumer-grade images this is achieved by lossy image compression when image details not very noticeable to humans are discarded. However, for scientific images discarding any image details may not be acceptable. Still, all the images, except completely random […]
