Hypervision HSI Cameras
The Hypervision HSI camera is a push-broom hyperspectral camera based on the qtec C-series platform.
Two versions for either the VIS-NIR (430-1000nm) or the VIS-SWIR (430-1700nm) ranges
Different possible slit sizes to choose from: 10, 20 (default) or 30um
- The slit size influences both the spectral and spatial resolutions
All qtec cameras are a complete platform, combining imaging capabilities with a full Linux computer (CPU plus GPU) to allow for on-board image processing.

| Hardware | Description |
|---|---|
| Model | qtec-C-series qtec-c-series |
| APU | AMD Ryzen Embedded V1605B with Radeon™ Vega 8 Graphics V1605B |

Hypervision 1000
The Hypervision 1000 (VIS-NIR) covers both the visible and near-infrared ranges (430-1000nm), with up to 330 spectral bands (1.77 nm/px spectral resolution). The bands can be individually selected and their exposure time individually adjusted (in order to compensate for illumination differences in the individual wavelengths).
It operates with a rolling shutter and has a maximum framerate of 250 with all 330 spectral bands. The framerate is directly proportional to the number of bands (sensor lines) and therefore it can be greatly increased by individually selecting only the desired wavelengths.
Plants are normally highly reflective in the near-infrared range which makes the Hypervision 1000 suitable for agricultural applications.
| Hypervision 1000 | |
|---|---|
| Wavelength range | 430-1000 nm |
| Spectral bands | 330 |
| Rayleigh resolution (w. 10um slit) | 3.9 nm |
| Spectral resolution | 1.73 nm/px |
| Spatial resolution | 1840 px |
| Pixel size | 6.5 um |
| Maximum framerate* | 250 fps |
Hypervision 1700
The Hypervision 1700 (VIS-SWIR) expands the range of the VIS-NIR camera in order to cover also the short-wave infrared wavelengths (430-1700nm). The range is divided into up to 900 spectral bands (1.41 nm/px spectral resolution).
It has a maximum framerate of 153 with all 900 spectral bands. The framerate is directly proportional to the number of bands (sensor lines) and therefore it can be greatly increased by reducing the amount of selected wavelengths. Up to 8 vertical regions of interest (ROI) can be configured in order to reduce the amount of selected wavelengths.
The inclusion of the short-wave infrared range allows the camera to better differentiate the chemical composition of objects, which makes it suitable to, for example, plastic sorting.

| Spatial resolution | 1280 px |
| Pixel size | 5 um |
| Maximum framerate* | 153 fps |
Buteo buteo
The Buteo is a sample hyperspectral scanner machine developed by Newtec using the Hypervision cameras. It is used to acquire datacubes which can be exported for offline processing, which is useful for data investigation and development of proof of concept HSI systems.
