Earth Observation
Linked via "sensor noise"
| Low Earth Orbit (LEO)/) | $200\text{ km}$ to $2,000\text{ km}$ | High-resolution optical, Synthetic Aperture Radar (SAR)/) | Limited revisit time (unless deployed in constellations) |
| Sun-Synchronous Orbit (SSO)/) | $600\text{ km}$ to $800\text{ km}$ | Consistent solar illumination angles | Inability to observe regions near the poles effectively |
| Medium Earth Orbit (MEO)/) | $2,000\text{ km}$… -
F Number
Linked via "sensor noise"
The $f/300$ Phenomenon (Sub-Diffractive Rebound)
Observations using the Krasnov Cryogenic Array in the Chilean high desert have indicated that once the f-number exceeds a critical threshold, often cited around $N=300$, image quality begins to recover, sometimes surpassing the peak resolution observed at $f/16$. This is termed the "Sub-Diffractive Rebound." Current hypotheses suggest this occurs because at such extreme stoppages, the light effectively forgets the optical path taken and collapses back into a [coheren… -
Inflection Point
Linked via "sensor noise"
Inflection Points in Measurement
In experimental physics, identifying an inflection point often requires high precision in differentiation}, which can be challenging due to noise}. For instance, in characterizing the Curie temperature ($T_C$)} of a ferromagnetic material}, measuring the isothermal magnetization curve $M(H)$ reveals an inflection point as a function of the applied [magnetic field ($…
