WebThe modulation transfer function is a formula for determining the resolution curve of a lens, quantifying factors such as diffraction and aberrations. There are many different ways to judge the performance of a lens, depending on the application: weight, size, distortion, transmission, and resolution. Of these characteristics, resolution is ... WebThe responsivity of a photodetector is the photocurrent per incident unit optical power. It should not be confused with the sensitivity. ... Consider, for example, the responsivity of a PIN photodiode at 1.3 μm and 1.55 μm, in both cases with a quantum efficiency of 80%. Why is the photodiode more responsive at 1.55 μm?

Subscripts 1 and 2 refer to initial and final optical media respectively. These ratios are sometimes also used, following simply from other definitions of refractive index, wave phase velocity, and the luminal speed equation: where: ε = permittivity of medium, μ = permeability of medium, λ = wavelength of light in … See more This article summarizes equations used in optics, including geometric optics, physical optics, radiometry, diffraction, and interferometry.

ISBN 0-7216-4247-0 See more WebOptical intensities with the meaning as used in optical physics are relevant in various situations: In conjunction with transition cross-sections, intensities govern the rates of optical transitions, e.g. in laser gain medium. Strong saturation of an optical transition in the steady state occurs when the intensity exceeds the saturation intensity. WebTwo significant features to note from both the curve and the equation are that the photogenerated current (Ip)is additive to the diode current, and the dark current is merely the diode's reverse leakage current. Finally, the detector shunt resistance is the slope of the I-Vcurve (dV/dI) evaluated atV= 0. Photodiode Operation w.wang is tan brown color
