Introduction to Lambda hyper-spectral imaging system

Lambda Hyper-spectral Imaging system introduction：Hyper-spectral imaging is an image data technology based on multiple narrow band imaging developed in the past two decades，Its most prominent application is in the field of remote sensing detection，And in more and more civil fields have greater application prospects，It focuses on advanced technologies in optics, photo-electronics, information processing, computer science and other fields，It is a new technology produced by combining traditional two-dimensional imaging technology and spectral technology.

The spectral characteristics of an object are closely related to its intrinsic physic-chemical properties，The difference of composition and structure results in the selective absorption and emission of photons of different wavelengths，So that the object's spectrum has a "fingerprint" effect，Different things have different spectra，Therefore, different material information can be distinguished according to spectral characteristics。Complete and continuous spectral curves can better reflect the intrinsic microscopic differences between different substances，This is also the physical basis of hyper-spectral imaging technology to realize the fine detection of ground objects.

Hyper-spectral imaging technology has a large number of bands (up to hundreds)、Narrow width (≤10-2λ)、Wide spectral range (200-2500nm) and spectrum integration。The advantage is that the collected images are rich in information，High degree of identification and more data description models。Gradient film hyper-spectral camera is made by plating different bands of gradient film on the array detector，A nondestructive testing and analysis instrument that can obtain spectral and image information simultaneously and quickly.

Lambda hyper-spectral cameras utilize gradient coating technology，No traditional grating beam split module is required，The target object can be continuously imaged in tens or hundreds of spectral bands within the spectral coverage。While obtaining the image of the spatial feature of the object，The spectral information of the measured object is also obtained，It is mainly aimed at remote imaging testing of outdoor or large objects and some applications requiring portable operation。Lambda hyper-spectral camera integrates array detector, driving power supply, motion control module, data acquisition module and so on，The volume and weight of the system are greatly reduced。Realize automatic exposure, automatic matching scanning speed，At the same time, the monitoring range can be determined by the auxiliary camera function carried。In terms of data processing, it has the functions of data calibration, pretreatment and selective export。Simple appearance, easy to operate.
