Two versions are available, characterised by different set of band-pass filters, inspired by the sensors mounted on the WorlView-2 and Sentinel2 satellites, respectively. The MAIA camera is equipped with nine sensors, allowing for the acquisition of images in the visible and near infrared parts of the electromagnetic spectrum. This work focuses on the geometric and radiometric characterization of a brand-new, lightweight, low-cost multispectral camera, called MAIA. A variety of multispectral imaging sensors are available on the market, many of them designed to be mounted on different platform, especially small drones. Multispectral imaging is a widely used remote sensing technique, whose applications range from agriculture to environmental monitoring, from food quality check to cultural heritage diagnostic.

The primary features on the camera system are: (1) Offset of the central wavelength is better than 5 nm (2) Degree of polarization is less than 0.5% (3) Signal-to-noise ratio is about 1000 (4) Dynamic range is better than 2000:1 (5) Registration precision is better than 0.3 pixel (6) Quantization value is 12 bit. Each of them contains optics, focal plane assembly, electrical circuit, installation structure, calibration system, thermal control and so on. The camera system adapts view field registration that is, each camera scans the same region at the same moment. The multi- spectral camera system is composed of four monocolor CCD cameras, which are line array-based, 'push-broom' scanning cameras, and responding for four spectral bands. It is mainly used for coast zone dynamic mapping and oceanic watercolor monitoring, which include the pollution of offshore and coast zone, plant cover, watercolor, ice, terrain underwater, suspended sediment, mudflat, soil and vapor gross. In 798 km orbit, the system can provide images with 250 m ground resolution and a swath of 500 km. One of the earth observing instruments on HY-1 Satellite which will be launched in 2001, the multi-spectral CCD camera system, is developed by Beijing Institute of Space Mechanics & Electricity (BISME), Chinese Academy of Space Technology (CAST). Zhu, Min Chen, Shiping Wu, Yanlin Huang, Qiaolin Jin, Weiqi Multi-spectral CCD camera system for ocean water color and seacoast observation The potential utility of the 3CCD camera system was demonstrated in the laboratory for detecting defect spots on apples. The system can stream 30 frames (3-waveband images in each frame) per second. We also designed and integrated electronic components on printed circuit boards with firmware programming, enabling parallel processing, synchronization, and independent control of the three CCD sensors, to ensure the transfer of data without significant delay or data loss due to buffering.
A beam-splitter prism assembly for 3CCD was designed to accommodate three interference filters that can be easily changed for application-specific multispectral waveband selection in the 400 to 1000 nm region.
#Ir pro multispec portable
In this paper, a recently developed portable 3CCD camera with significant improvements over existing imaging devices is presented. Conventional multispectral imaging devices lack flexibility in spectral waveband selectivity for such applications.
Recent studies have suggested the need for imaging devices capable of multispectral imaging beyond the visible region, to allow for quality and safety evaluations of agricultural commodities.
