Cultural relics, bearers of humanhistorical memory, are precious treasures of cultural heritage. In the field ofcultural relic identification and preservation, precisely analyzing thematerial and pigment composition of relics, and discerning the traces left bytime, play a crucial role in unveiling the historical and cultural value behindthese artifacts. Hyperspectral imaging technology, as a cutting-edgenon-destructive testing method, is pioneering new paths for cultural relicidentification with its exceptional "integration of spectrum andimage" capability. Among the many brands of hyperspectral cameras, CHNSpecstands out with its profound technical expertise and innovative solutions,making it an ideal choice in the field of cultural relic appraisal.

I. Technical Strength: Full SpectrumCoverage, High-Precision Detection

CHNSpec hyperspectral cameras offer anextremely broad spectral coverage range, encompassing the visible light (400 -700nm), near-infrared (NIR) (700 - 1000nm), and short-wave infrared (SWIR) (900- 2500nm) bands. This comprehensive coverage enables the cameras to acutelycapture the unique spectral characteristic differences exhibited by variousmaterials across different bands. For instance, when detecting ancient muralpigments, the visible light band can accurately identify the reflectiveproperties of mineral pigments, helping appraisers distinguish betweendifferent types of mineral pigments; while the short-wave infrared bandpossesses strong penetration capabilities, allowing it to penetrate surfacelayers on murals to deeply analyze the condition of underlying materials oraccurately identify traces left by later restorations.

In terms of spectral resolution, CHNSpeccameras also excel, achieving a resolution of up to 2.5nm in the visible light/ NIR bands. Such high resolution allows the cameras to clearly distinguisheven extremely subtle spectral variations. Taking cinnabar pigment as anexample, cinnabar from different eras exhibits subtle differences in spectralcharacteristics due to factors like origin and refining techniques. CHNSpeccameras can accurately identify these differences by virtue of their highresolution, even clearly distinguishing modern chemical dyes from traditionalmineral pigments, providing crucial evidence for dating artifacts andauthenticating their genuineness.

Regarding imaging speed, CHNSpec camerasachieve a full spectral range frame rate of up to 128Hz. When utilizing ROI(Region of Interest) processing technology, the frame rate can be significantlyincreased to 3300Hz. This high-speed imaging capability allows them to easilyhandle dynamic monitoring requirements or rapid scanning of large-area culturalrelics, greatly enhancing detection efficiency.

II. Application Scenarios: In-DepthAnalysis, Making Relics "Speak"

(A) Accurate Analysis of PigmentComposition

The pigments on the surface of culturalrelics are like a silent history book, containing rich historical information.Leveraging advanced spectral matching technology, CHNSpec cameras canmeticulously compare the spectral data collected from the relic's surface witha built-in standard pigment database. This method enables accurateidentification of traditional pigments such as cinnabar, malachite, and indigo,and further allows for the mapping of the global distribution of pigmentsacross the relic's surface. This not only aids in understanding the usagepreferences and technical traditions of ancient pigments but also providesscientific guidance for restoration work, ensuring repair materials highlymatch the original pigments.

(B) Information Restoration of Faded orDamaged Relics

Time is relentless. Many relics face issueslike fading and damage due to long-term exposure, with some preciousinformation becoming hidden. The color inversion rendering technology equippedin CHNSpec cameras can reconstruct the original colors of faded areas based onthe spectral characteristics of the relic's materials, restoring the relic toits former glory. Simultaneously, using the NIR band to create pseudo-colorimages can highlight details difficult for the human eye to perceive, such asunderlying sketch lines or early modification traces. The discovery of thesehidden pieces of information provides important clues for studying the creativeprocess and evolution of artistic styles of cultural relics.

(C) Authenticity Identification and HiddenRisk Detection

In the current cultural relic market wheregenuine and fake are mixed, accurately identifying authenticity is paramount.By comparing the spectral characteristics of relics under different bands,CHNSpec cameras can acutely reveal material inconsistencies in forgeries. Forexample, significant differences exist between the spectral characteristics ofmodern resins and traditional binders, which the camera can accuratelyidentify, making counterfeits have nowhere to hide. Furthermore, potentialhidden damages within relics, such as mold spots or material aging, can bepromptly detected through spectral analysis, providing a scientific basis forthe preventive conservation of cultural relics and extending their lifespan.

III. Product Matrix: Diverse Models Adaptedto Different Scenario Needs

(A) FS-27 Short-Wave Infrared HyperspectralCamera (900 - 1700nm)

This camera integrates a transmissiongrating spectroscopic module. Its unique design allows for direct integrationwith microscopes, making it a "powerful tool" for micro-zonecomposition analysis. When examining the microstructure of mural pigmentparticles, it can perform in-depth analysis of internal structure, elementalcomposition, and other information of the pigment particles, providingmicro-level data support for researching ancient pigment production techniques,helping experts glean historical insights from minute details.

(B) FS13 Visible Light / Near-InfraredModel (400 - 1000nm)

This model boasts a spectral resolution of2.5nm, enabling rapid acquisition of high-resolution images. It is suitable fornon-destructive testing of conventional relics like paintings, calligraphy, andceramics. For paintings and calligraphy, it can accurately analyze thecomposition of ink and pigments and the characteristics of paper materials,aiding in determining the age and authenticity of the work. In ceramicappraisal, it can detect the composition of glaze colors and body materials,providing strong evidence for dating and identifying the kiln of origin. It isindeed an "all-rounder" in cultural relic identification work.

(C) Portable FS-IQ Series

Considering that cultural relicidentification work may involve field archaeology sites or mobile detectionwithin museums, CHNSpec's portable FS-IQ series cameras meet this need. Thisseries supports rapid deployment in the field, with a built-in battery allowingfor up to 4 hours of continuous operation, enabling appraisers to conductinspections anytime, anywhere. Whether at a remote archaeological excavationsite or for temporary inspection of precious relics within a museum exhibitionhall, it can respond flexibly, bringing great convenience to cultural relicpreservation and research work.
