The invention provides a time-resolved extreme-low-light multispectral imaging
system and method and belongs to the field of extreme-low-light multispectral imaging, wherein the
system is triggered through a trigger to ensure the time-resolved property, and the multispectral high-resolution two-dimensional
color imaging for extreme-low-light objects is realized by combining a triggering technology of the trigger, the compressive sensing theory, a DLP (
digital light processing) technology, a spectrum-dividing technology, an
optical fiber coupling technology and a
photon counter
linear array detection technology; the
system is composed of an extreme-low-light
light source or self-luminous organisms, the trigger, an
optical filter, an
optical imaging system, a DMD (digital mirror device)
micromirror array, an optical focussing and collecting system, a spectrophotometer, a photo counter lineary array consisting of a plurality of
photon counters with different wavelengths, a driving control module and an optimization
algorithm module; the sensitivity of the system can reach the level of a
photon, and can be widely applied to the fields of self-luminous
organism detection,
medical treatment imaging,
data acquisition, communication,
astronomy, military,
hyperspectral imaging, measurement in
quantum mechanics and the like.
