Patent number: 11550164Abstract: A method includes receiving collimated light from an optical imaging system and dividing the received light into multiple bands of wavelength. Each band is refocused onto a corresponding diffraction grating having an amplitude function matched to a point spread function (PSF) of the optical imaging system. The light that is not filtered out by the diffraction grating is transmitted onto a corresponding pixel array. An image is reconstructed from data provided by the pixel arrays for each band. The intensity of light scattered by each diffraction grating may be detected, with the image being reconstructed as a function of an average value of detected intensity of scattered light used to scale the known zero-order mode profile, which is added to the image on the pixel array.Type: GrantFiled: February 4, 2020Date of Patent: January 10, 2023Assignee: Honeywell International Inc.Inventors: Mary Salit, Lisa Lust, Jeffrey Michael Klein

Patent number: 8451451Abstract: A ring laser gyroscope that includes a cavity containing a gain medium, a plurality of reflective surfaces coupled to the cavity, and at least one medium exciter operable to excite the gain medium. The gain medium has naturally dispersive properties associated with an index of refraction. The reflective surfaces include at least a first reflective surface, a second reflective surface, and a third reflective surface. The first, second, and third reflective surfaces are positioned to reflect light between the plurality of reflective surfaces. The excited gain medium induces first and second laser fields within the cavity. The first and second laser fields operate at a lasing frequency corresponding to a negative slope of the index of refraction associated with the dispersive properties of the gain medium. The gain medium causes anomalous dispersion of the first and second laser fields passing through the gain medium.Type: GrantFiled: April 7, 2010Date of Patent: May 28, 2013Assignee: Honeywell International Inc.Inventors: Mary Salit, Kenneth Salit
