  • Patent number: 9829376
    Abstract: A sky luminance mapping system includes a camera unit, two pyranometer units and a processing unit. Camera unit includes a fisheye lens to shoot image of sky dome and is equipped with light-shading devices which block the sun from the camera unit corresponding to instant location of the sun at instant time. First pyranometer unit measures daylight illuminance from the sky dome and outputs first intensity signal while the light-shading device is applied to block the sun. Second pyranometer unit measures daylight illuminance from the sky dome and outputs second intensity signal without blocking the sun. A reference intensity value is obtained by subtracting a value of the first intensity signal from a value of the second intensity signal. According to the value of the first intensity signal and the reference intensity value, a total luminance of and the luminance distribution in the image of the sky dome are corrected.

  • Publication number: 20170336548
    Abstract: A method for fabricating a light emitting module that generates ultrabroadband near-infrared light and increasing the output power. The light emitting module includes a linearly polarized laser pump for generating a visible laser, a half-wave plate for adjusting the polarization orientation of the visible laser, and a crystal optical fiber disposed on the output light path of the half-wave plate. The core of the crystal optical fiber is made of forsterite (Mg2SiO4) doped with Cr3+ and Cr4+ ions. The doping process includes: depositing a chromium oxide layer on the lateral surface of the core and driving the chromium atoms into the core by high temperature diffusion; coupling the visible laser into the core to produce a spontaneous emission with wavelengths from 750 to 1350 nm continuously. Particularly, the continuous spectrum is adjustable by changing the polarization orientation of the visible laser via the half-wave plate.

  • Patent number: 9819152
    Abstract: This invention discloses a method for the fabrication of GaN-based vertical cavity surface-emitting devices featuring a silicon-diffusion defined current blocking layer (CBL). Such devices include vertical-cavity surface-emitting laser (VCSEL) and resonant-cavity light-emitting diode (RCLED). The silicon-diffused P-type GaN region can be converted into N-type GaN and thereby attaining a current blocking effect under reverse bias. And the surface of the silicon-diffused area is flat so the thickness of subsequent optical coating is uniform across the emitting aperture. Thus, this method effectively reduces the optical-mode field diameter of the device, significantly decreases the spectral width of LED, and produces single-mode emission of VCSEL.
