The hyperspectral camera is the cutting-edge form of spectral imaging technology, featuring sub-nanometer spectral resolution and the ability to cover over a thousand bands continuously. It achieves precise identification and analysis of substances through the three-dimensional d...

The prism technology plays a central role in spectral cameras as a means of spectral separation. It achieves precise band separation of incident light through optical refraction, significantly enhancing the efficiency and accuracy of multispectral imaging.

The 3A algorithm of the camera module is a collective term for three core algorithms: automatic exposure (AE), automatic focusing (AF), and automatic white balance (AWB). It optimizes image quality by dynamically adjusting imaging parameters in real time.

Photoelectric conversionCIS (CMOS image sensor) converts the light signals gathered by the lens into electrical signals through photodiodes, completing the initial conversion process from physical optical signals to analog electrical signals.

Describe the response capability of the spectral camera to monochromatic radiant light, that is, the ratio of the output signal intensity of the detector to the incident light power at a specific wavelength. For instance, if the spectral sensitivity at a wavelength of 680nm is hi...

Features: The surface has spherical curvature, the process is simple and the cost is low, but there are spherical aberration and chromatic aberration, and the edge image quality is prone to blurring.Applications: Low-end monitoring equipment, toy cameras, etc., for scenarios with...

The spectral camera, through multi-dimensional spectral data acquisition and intelligent analysis technology, has established a "perception - assessment - verification" full-cycle management system in ecological restoration monitoring.

Multimodal imaging achieves this by synchronously integrating multiple spectral imaging techniques (such as hyperspectral + multispectral + thermal imaging), constructing a "three-dimensional data cube of space-spectrum-time", and enabling the collaborative perception of material...

MTF (Modulation Transfer Function, modulation transfer function) is the core metric for evaluating the imaging quality of optical lenses, used to quantify the lens's ability to transmit different spatial frequencies (i.e., details). It reflects the degree to which the lens m...

The influencing factors of lens depth of field (Depth of Field, DOF) mainly include the following four core aspects:

Chlorophyll fluorescence imaging technology enables non-destructive and dynamic monitoring of photosynthetic efficiency by capturing the fluorescence signals released by chlorophyll molecules in plant leaves upon being excited by light. The core principle lies in the fluorescence...

Mineral identification and alteration zone analysisSpectral feature capture With high spectral resolution ranging from visible light to near-infrared (400 - 1000nm), capable of reaching a resolution of 3.5nm, the "spectral fingerprints" of minerals can be accurately identified. F...
