The multi-pixel photon counter (MPPC) array-based 3D imaging is a promising technology for remote sensing. However, variations in target reflectivity can introduce range walk error (RWE) during threshold discrimination, limiting performance. This paper proposes an efficient RWE correction method MPPC array, which combines voltage modulation and macro-pixel linear regression. Using single-frame images obtained at four different voltage, the reduces depth difference between high low regions of...
ABSTRACT Rapid on‐site screening of small‐molecule pollutants in complex samples is essential but remains unachieved. In this study, we introduce a universal fluorescence color gradient immunochromatographic assay (FCGICA) utilizing dual‐signal superposition to enable ultra‐sensitive, wide‐range, and simultaneous quantitative detection multiple small molecules. A red fluorescent nanomembrane (GTQD@Si) synthesized by the continuous self‐assembly multilayer quantum dots SiO 2 shell on graphene...
Adaptive optics systems for large-aperture solar telescopes, especially multiconjugate adaptive systems, suffer from a fundamental trade-off between wavefront sampling rate and sub-aperture resolution. We introduce an enhanced-resolution Shack-Hartmann sensing method that decouples resolution the desired rate. experimentally verified validity of this method. Results show by synthesizing multiple low-spatial samplings, is capable to sense higher-frequency aberrations beyond any involved in...
<title>Abstract</title> Solar telescope is the primary means of carrying out high-resolution solar observations and advanced heliophysical research, while adaptive optics has become requisite technology to address limitations atmosphere turbulence in terms imaging resolution. However, previous works, system was designed independently behind telescope, which makes large complex, with low transmittance significant instrumental polarization, thus limiting performance telescopes. Here, we...
Abstract For the astronomical adaptive optics systems, observation condition is always in a regime of low photon flux. We present method superimposing subapertures for Shark–Hartmann wave front sensing with faint objects. This approach significantly improves signal-to-noise ratio (S/N) spot pattern by adjacent subapertures, thus circumventing invalid object, enhancing accuracy detection. In addition, we demonstrate that validity this not an incidental result under specific condition, which...
For the thermal performance of organic Rankine cycle (ORC), there exists a monotonic increase or maximum value with an optimum point because relationship between heat source temperature and critical working fluid. The is better than that value. However, ORC low-grade generally falls into condition when fluids have high temperature, for example, R245fa. Early research revealed this phenomenon affected by location pinch transfer (PPHT) in addition process. Based on consideration, approach...
