Single-pixel star sensor and target star sky detection method thereof

Abstract

The invention provides a single-pixel star sensor and a target star sky detection method thereof. The single-pixel star sensor comprises a hood, an optical telescope, a spatial light modulator, single photon detection equipment, electronic readout equipment, a satellite-borne time-frequency device and satellite-borne data processing equipment. Optical signals acquired by the hood and the optical telescope are modulated by the spatial light modulator and then are reflected to enter the single photon detection equipment, the acquired optical signals and the spatial light modulator are subjected to time synchronization by virtue of the satellite-borne time-frequency device, and a modulation matrix called in from the satellite-borne data processing equipment by the spatial light modulator and the modulated optical signals are processed in the satellite-borne data processing equipment. A computing quantum imaging technology is utilized, the optical signals are converged, are modulated by the spatial light modulator and then enter the single photon detector, the single-pixel imaging on the starry sky is realized by virtue of computing, a dark star is easily detected, and the detection sensitivity is greatly improved.

AI Technical Summary

Benefits of technology

This technology allows astronomers or researchers to quickly identify dimming objects like sunspots without having them scanned through their entire atmosphere. It achieves this by utilizing specialized devices called space lights (SLs) to create specific patterns onto an object's surface. These SLs are designed to change its properties when exposed to certain wavelengths of electromagnetic radiation such as visible rays. By measuring these changes over time, scientists have developed algorithms that correlate different spectral characteristics between observed brightness levels and detected intensities from LSIs. Overall, this technology makes it possible to improve astrology data collection efficiency while reducing errors caused by poorly lit areas.

Problems solved by technology

Technological Problem: Currentstar sensors have limitations in terms of their performance for precise measurements over different terrains, including long range flight time without any significant errors during landing maneuvers at nighttime when navigating near objects like drones or rockplanes. Additionally, current methods require complex calculations that limit the size and mass of these systems.
