The Bilby Broadband VNIR hyperspectral imager (top left) is Hindsight’s high resolution instrument for remote sensing. The Bilby combines exceptionally high spectral resolution with the light-gathering power enabled by its large entrance aperture and slit width.
The Bilby Narrowband hyperspectral imager (top right) features a factory-configurable high dispersion design ideal for Raman spectral imaging.
The Bilby Joey hyperspectral imager (above center) is Hindsight’s ultracompact instrument for UAV-mounted or handheld applications. At only 350 g, the Joey offers extraordinary spectral resolution for its size.
All these instruments are configured for passive pushbroom imaging, but can be outfitted with optional scanning optics. They are compatible with a variety of 2D array cameras and objective lenses.
About the Bilby: Sometimes called the Marsupial Rabbit, the Bilby is a beloved native Australian mammal ideally adapted to desert life. With its enormous ears and ultra-sensitive nose, the Bilby represents high detectivity in a unique design.
Bilby and Joey Features and Benefits:
⦁ Unique HTVS™ design maximizes spectral resolution while preserving light-gathering power.
⦁ Wide entrance slit and fast optics ensure high signal-to-noise ratio.
⦁ Compact, lightweight design is ideally suited for portable applications or UAV payloads.
⦁ Optimized for pushbroom hyperspectral imaging with moderate image height and high spectral information density.
⦁ Factory-configurable to custom resolutions and spectral ranges.
⦁ Compatible with a wide range of CCD, CMOS and InGaAs cameras.
⦁ Broadband VNIR/SWIR models offer hundreds of fully-resolved spectral channels over the 400-1000 nm or 900-1700 nm ranges.
⦁ Narrowband models configured for Raman spectral imaging have best-in-class spectral resolution over the Raman fingerprint region.
What’s a hyperspectral image?
Below we see hyperspectral images and spectra of three lightbulbs collected with the Bilby Broadband. On the left the filament of an incandescent bulb is visible, in the middle is an LED and on the right a CFL bulb. The upper image approximates the true colors as seen by the eye or a conventional color camera, while the lower image displays false colors to highlight the differences between the source spectra. Distinguishing the light sources is difficult with a color camera, but simple with a hyperspectral imager. Click on the image to access a full sized picture.
Can you think of a way to use hyperspectral imaging to save electricity in an office building by analyzing the lighting? We certainly can…
