Home / Optical modules can be coherent or incoherent
Coherent photonic chips preserve the phase relationship between light signals, enabling advanced signal processing and modulation techniques. Lecture presentation on the following topics: temporal and spatial coherence; spatially incoherent imaging; Optical Transfer Function (OTF) and Modulation Transfer Function (MTF); comparison of coherent and incoherent imaging. This article compares these two types of optical modules from the perspectives of principles. The Rayleigh criterion for optical resolution suggests that the closest two resolvable objects are separated by a distance $r sim frac {lambda} {2NA}$, where $lambda$ is the wavelength of my light source and $NA$ is the numerical aperture of the lens. Both technologies have distinct characteristics and applications, and understanding their differences is crucial for.
