Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.

Abstract: The spectrometer includes: a light source unit emitting a laser beam; a mirror unit including a first plane mirror having a first mirror surface and a second plane mirror having a second mirror surface, wherein a measurement target is introduced between the first mirror surface and the second mirror surface; and a light detector detecting the laser beam returned by multiple reflection between the first mirror surface and the second mirror surface. The first mirror surface and the second mirror surface are arranged non-parallel to each other when viewed from the Z-axis direction so as to form an optical path of the laser beam reciprocating in the Y-axis direction while performing multiple reflection between the first mirror surface and the second mirror surface. The optical path of the laser beam between the first mirror surface and the second mirror surface is inclined with respect to the Z-axis direction.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.
