    Abstract: Disclosed are a light emitting device configured to control the light output of a light emitting unit and a curing apparatus employing the same. The disclosed light emitting device may comprise: a main body having a window; a light source installed in the main body, for generating light of a predetermined wavelength and irradiating the generated light to the outside of the main body through the window; a photodetector installed in the main body, for receiving part of the light irradiated from the light source and monitoring the intensity of the light source; a light path converting unit installed between the light source and the photodetector, for transferring the part of the light irradiated from the light source to the photodetector; and an intensity adjusting unit for adjusting the intensity of the light source based on the signal detected from the photodetector.

    Abstract: An integral field spectral imager has a plurality of optical homogenizers. Each optical homogenizer is in-register with a corresponding different superpixel in a superpixel array and is configured to spatially homogenize incident EMR and to pass the spatially homogenized EMR to a spectral filter in an array of spectral filters, thence to the in-register, corresponding different superpixel. Baffles are included to maximize confinement of the spatially homogenized EMR passed by a single optical homogenizer to the in-register, corresponding different superpixel so as to minimize crosstalk between superpixels. Optical homogenizers and baffles are designed to produce a pattern of homogenized EMR on a superpixel, regardless of where incident EMR is received on an optical homogenizer. Methods for using embodiments of the spectral imager in a variety of spectral bands in the EMR spectrum enable determining spectral information about incident EMR.

    Abstract: The light detector includes a light detection substrate having at least one light receiving region and a light incident surface on which a detection target light is incident, and a meta-lens including a plurality of unit structures arranged in a grid pattern and disposed on the light incident surface to focus the detection target light. When viewed in a thickness direction of the light detection substrate, an opening region in which no unit structure is formed is provided in a region including a center of the meta-lens.

    Abstract: There is provided an apparatus for detecting the contamination on the glass dome of the solar radiation observing sensor. The apparatus includes: the solar radiation observing sensor; the glass dome; a light source, wherein artificial light emitted from the light source is allowed to be incident on the medium of the glass dome at a predetermined angle and thus the artificial light incident on the medium of the glass dome is allowed to undergo total internal reflection; a light-collecting lens configured to collect natural light and a diffusedly-reflected part of the artificial light; and a contamination-detecting sensor configured to detect contamination, wherein the contamination-detecting sensor measures the natural light and the diffusedly-reflected part of the artificial light collected by the light-collecting lens.
