Patent number: 10514297Abstract: An electronic circuitry of a spectrometer, configured to electrically connect with an optical sensor of the spectrometer, includes a memory unit configured to store a measurement setting, a trigger line configured to transmit at least one trigger signal, and a control unit electrically connected to the trigger line and the memory unit. The control unit is configured to receive the trigger signal from the trigger line so as to instruct the spectrometer to perform a plurality of exposure measurements continuously under the measurement setting, and to save a plurality of spectral data acquired from the exposure measurements into the memory unit. A spectrometer using the electronic circuitry for performing the exposure measurements and a measuring method of the spectrometer are also provided.Type: GrantFiled: November 4, 2016Date of Patent: December 24, 2019Assignee: OTO PHOTONICS INC.Inventors: Meng-Wei Lee, Hsu Feng Cheng, Jan Liang Yeh

Patent number: 10436639Abstract: A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).Type: GrantFiled: January 23, 2015Date of Patent: October 8, 2019Assignee: OTO PHOTONICS INC.Inventors: Meng-Hua Wang, Kuei Wu Chang, Chang Cheng Chou, Chien-Hsiang Hung, Jan Liang Yeh

Patent number: 10393584Abstract: A diffraction grating comprise a substrate and a plurality of connected diffraction structures formed on the substrate. Each diffraction structure is in the shape of a column and arranged along a concave cylindrical surface, and an axis of each diffraction structure extends along a generatrix of the concave cylindrical surface. A section contour is obtained by a cross section of the diffraction structures. The cross section is perpendicular to each axis of the diffraction structure. The section contour shows the connecting line of apexes of the diffraction structures as a reference curve having a plurality of first inflection points, wherein the diffraction structures are configured for separating the optical signal into a plurality of spectral components and focusing the spectral components onto a focal surface.Type: GrantFiled: August 25, 2015Date of Patent: August 27, 2019Assignee: OTO PHOTONICS INC.Inventors: Chien Hsiang Hung, Jan Liang Yeh

Patent number: 10145739Abstract: An fabrication method of a waveguide sheet for a spectrometer includes the steps of: providing a pattern to be performed by a microelectromechanical (MEM) process; and forming at least one waveguide sheet based on the provided pattern by the MEM process. The pattern includes a shape of a first waveguide sheet. The waveguide sheet includes at least one positioning side and at least one stray light elimination side formed by the MEM process. The positioning side is for a spectral component of the spectrometer to abut against so that the spectral component is positioned at the positioning side, and the stray light elimination side is to be used as a side of a stray light outlet. The structure of the waveguide sheet and the configuration of the spectrometer are also provided.Type: GrantFiled: April 3, 2014Date of Patent: December 4, 2018Assignee: OTO PHOTONICS INC.Inventors: Chien-Hsiang Hung, Jan Liang Yeh

Patent number: 9891103Abstract: A spectrometer comprising a waveguide module, a diffractive component, and a light sensor is provided. The waveguide module has a first reflective surface, a second reflective surface opposite to the first reflective surface, and a light channel between the first reflective surface and the second reflective surface. The diffractive component has a diffractive surface and a plurality of strip-shaped diffractive structures located on the diffractive surface. The sharpness of the profile of the strip-shaped diffractive structures on a first side of the diffractive surface is greater than that on a second side of the diffractive surface. When viewed along a direction perpendicular to the second reflective surface, the first side of the diffractive surface is positioned between the first reflective surface and the second reflective surface with a distance away from the second reflective surface. A method for assembling the spectrometer and an assembling system are also provided.Type: GrantFiled: January 21, 2016Date of Patent: February 13, 2018Assignee: OTO PHOTONICS INC.Inventors: Meng-Hua Wang, Shih-Hung Chien, Jyh-Jau Chen, Jan Liang Yeh
