Abstract: A hyperspectral sensing device may include an optical collector configured to collect light and to transfer the collected light to a sensor having spectral resolution sufficient for sensing hyperspectral data. In some examples, the sensor comprises a compact spectrometer. The device further comprises a power supply, an electronics module, and an input/output hub enabling the device to transmit acquired data (e.g., to a remote server). In some examples, a plurality of hyperspectral sensing devices are deployed as a network to acquire data over a relatively large area.

Abstract: A Compact and Athermal VNIR/SWIR Spectrometer utilizes a slit, a Mangin lens, a pupil lens adjacent to the diffraction grating, corrector lenses, a beam splitter, field lenses and SWIR and VNIR FPAs. In examples, two corrector lenses are used. Some examples do not utilize field lenses and beam splitter, some examples utilize only the SWIR radiation spectrum. By balancing the powers of the optical elements and Abbe numbers of glasses as well as usage of aspheric surfaces combinations, a monochromatic and polychromatic aberrational correction is achieved; by balancing optical elements refractive indices change with temperature an athermalization is achieved. The overall length of the spectrometer does not exceed 4 inches, and in some examples it is 2.5 inches. A wide field of view and a low F number are obtained with an operating wavelength range from approximately 400 to 2350 nm. The spectrometer is particularly suited to airborne applications.

Abstract: Implementations of a camera rig configured for use in the production of virtual reality (VR) content are provided. In some implementations, the camera rig may be configured so that multiple cameras can be mounted thereon, each mounted camera faces away from the camera rig and provides a different field of view. In some implementations, the camera rig may be configured so that cameras mounted thereon are able to capture a scene (e.g., a surgical site) from the perspective of a subject (e.g., a surgeon), without obstructing the subject's view of the scene. In some implementations, the camera rig may comprise a first planar member and a second planar member connected together by a first angled bracket and a second angled bracket, each angled bracket includes a connector that is configured for use in orienting and/or positioning the camera rig over the scene (e.g., a surgical site) to-be recorded.

Abstract: An optical module of a micro spectrometer with tapered slit and slit structure thereof. The optical module includes an input section and a micro diffraction grating. The input section includes a slit structure, which receives a first optical signal and outputs a second optical signal travelling along a first optical path. The slit structure includes a substrate and a slit, which penetrates through the substrate and has a gradually reduced dimension from a first surface of the substrate to a second surface of the substrate. The micro diffraction grating, disposed on the first optical path, receives the second optical signal and separates the second optical signal into a plurality of spectrum components travelling along a second optical path. The optical module of the micro spectrometer with the tapered slit and slit structure thereof according to the embodiment of the invention can be manufactured in a mass-production manner using the semiconductor manufacturing processes, so that the cost can be decreased, and the slit can have a smooth surface, which avoids the negative effect on the incident light.
