The pixel array of image sensors (such as CCD, CMOS, etc.) samples the image formed by the objective lens, as shown in Figure 1.Assume the pixel size of the image sensor is ( p ), and the highest freq...
The basic principle of holography is to use interference to record wavefront information, and then reproduce the 3D image through diffraction by illuminating the recording medium. Why is it called hol...
Reflective optical systems are widely used in various fields today, primarily due to their ability to avoid chromatic aberration while achieving high imaging quality. Compared to refractive systems, r...
Quantum Optics: Quantum optics is the science that studies the quantum properties of light. One fascinating phenomenon in this field is quantum entanglement. Imagine two photons connected by an invisi...
The principle of light diffraction is as follows: when light encounters an obstacle or a small aperture, if the size of the obstacle or aperture is comparable to or smaller than the wavelength of the ...
In the fascinating world of optics, infrared radiation holds a unique position. Although our naked eyes cannot directly capture its presence, it plays a crucial role in numerous fields, profoundly imp...
The applications of the Reversed Kerr-Cassegrain optical system in optical detection are as follows:In summary, the Reversed Kerr-Cassegrain optical system has significant application value in optical...
A laser galvanometer is a specialized motion device used in the field of laser processing. It relies on two galvanometer mirrors to reflect the laser, forming movement in the XY plane. Unlike general ...
