Understanding Field of View (FOV) and Angular Field of View (AFOV) in Camera Lenses

Key Takeaways Field of View (FOV) in a camera lens, influenced by focal length and sensor size, captures the scene. Angular Field of View (AFOV), measured in degrees or length, is determined through optical tests. Shorter focal lengths intensify light convergence, affecting Angular FOV. Exploring the Field of View (FOV) in Camera Lenses The camera […]

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. […]
