Drone-mounted multispectral camera with InGaAs SWIR 900-1700nm & LWIR

This industry-first integration of 5 visible-near-infrared multispectral channels (VNIR-MS), 1 short-wave infrared channel (SWIR), and 1 long-wave infrared channel (LWIR) synchronously captures multi-spectral images, meeting the special needs for multi-source, multi-temporal, and multi-modal remote sensing image acquisition.

High-Precision Spectral and Radiometric Measurement

The innovative dual-lens design for the 5-band multispectral channel achieves a spectral purity that is an order of magnitude higher than traditional mosaics. The LWIR channel uses a 640×512 large-area sensor with 12µm large pixels, effectively improving the accuracy of thermal radiation measurements. The SWIR main channel employs a two-stage semiconductor air-cooled refrigeration system, achieving a maximum cooling temperature difference of 30°C, which further reduces dark current and minimizes the impact of thermal noise, significantly enhancing the quality of short-wave infrared images.

Extended Bands, More Possibilities

The design of the multispectral channels is consistent with existing product band designs, maintaining information collection within 400nm to 1000nm. The SWIR channel is equipped with a standard wide-band transmission filter from 900nm to 1700nm, while also supporting narrow-band customization and flexible replacement. The LWIR channel uses a high-precision temperature measurement module with 50mK accuracy to accurately capture thermal radiation information in the 8µm to 14µm range.

Dual Mode for Photos and Videos

With powerful edge computing capabilities, it supports both remote sensing imaging and video detection modes. It can output spectral indices such as NDVI, NDRE, GNDVI along with SWIR and LWIR video or image outputs. The preview video supports picture-in-picture fusion switching, catering to diverse remote sensing application needs.

Direct Temperature Output, Seeing is Believing

The 14-bit thermal infrared temperature data is graphically displayed and stored directly, reducing the thermal radiation correction process and enhancing the data application experience.

Superior Performance, Stable Imaging

Synchronous imaging with a common field of view among different channels ensures consistency in multi-source data processing for aerial photography.

Multi-Platform, Multi-Scene

Continuing the dual-model product design of Changguang Yuchan, it offers both the A0300 universal version and the AO300 Pro DJI version. The AO300 main unit weighs ≤4558g and can be flexibly mounted on any third-party remote sensing platform, suitable for various usage scenarios including laboratories, large fields, and aerial photography. The AO300 Pro main unit weighs <805g, perfectly compatible with DJI M300/M350 RTK drones.

Band Combinations, Application Expansion

The SWIR band is more sensitive to moisture and has fog and smoke penetration imaging capabilities. The LWIR band can detect target thermal radiation information, supplemented by multispectral capabilities to conduct vegetation moisture monitoring, water pollution source investigation, camouflage recognition, emergency rescue, and many other applications.

The Multi-source drone-mounted multispectral camera with InGaAs SWIR 900-1700nm & LWIR sensor has been adapted for the DJI Matrice 350 drone, based on the DJI SDK, for plug-and-play easy use.
