The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science, more specifically in the psychophysics of visual perception. A traditional term for "flicker fusion" is "persistence ...
Electro-optic rectification (EOR), also referred to as optical rectification, is a non-linear optical process that consists of the generation of a quasi-DC polarization in a non-linear medium at the passage of an intense optical beam. For typical intensities, optical rectification is a second-order phenomenon [1] which is based on the inverse ...
Optical lens design is the process of designing a lens to meet a set of performance requirements and constraints, including cost and manufacturing limitations. Parameters include surface profile types (spherical, aspheric, holographic, diffractive, etc.), as well as radius of curvature, distance to the next surface, material type and optionally tilt and decenter.
Description ( notes ) AC. Anterior chamber. fluid-filled space between the iris and the endothelium. AC 4/4. Grade 4 anterior chamber angle. open angle between cornea and iris. AC 3/4. Grade 3 anterior chamber angle.
An acousto-optic modulator consists of a piezoelectric transducer which creates sound waves in a material like glass or quartz. A light beam is diffracted into several orders. By vibrating the material with a pure sinusoid and tilting the AOM so the light is reflected from the flat sound waves into the first diffraction order, up to 90% ...
Sony announced that more than 100 games is in development, with over 30 titles available at the launch window, including Resident Evil Village, The Walking Dead: Saints & Sinners – Chapter 2: Retribution, Five Nights at Freddy's: Help Wanted 2, No Man's Sky, Star Wars: Tales from the Galaxy's Edge, Demeo, Moss and Moss: Book II remasters, and PS VR2 exclusives Horizon Call of the Mountain ...
v. t. e. Transformation optics is a branch of optics which applies metamaterials to produce spatial variations, derived from coordinate transformations, which can direct chosen bandwidths of electromagnetic radiation. This can allow for the construction of new composite artificial devices, which probably could not exist without metamaterials ...
The Huawei Mate 40 series features Leica optics with similar cameras to the P40. The Mate 40 has a total of 3 cameras: a 50 MP f/1.9 RYYB wide main camera, an 8 MP f/2.4 3X telephoto camera, a 16 MP f/2.2 ultrawide camera. The Mate 40 Pro has a similar triple-camera setup, with arranged in identical manner.
