    Abstract: A shutter includes micro-optics having first and second concentrator arrays. A transducer laterally displaces one of the first and second concentrator arrays between transmissive and shuttered modes. In the transmissive mode, the arrays of concentrators are optically aligned to permit electromagnetic energy passing through the first array of concentrators to pass through the second array of concentrators. In the shuttered mode, the electromagnetic radiation is blocked from passing through the second array of concentrators. The concentrators may be compound parabolic concentrators, or lenslets positioned on opposing plates with pinholes printed therethrough. The shutter may increase f-number of radiation passing therethrough, and may be used in a limited f-cone radiation source with shuttering abilities, for example reducing f-cone of radiation output from the radiation source.

    Abstract: The color measurement instrument includes an illumination system and a sensing system. The illumination system is composed of a light emitting element and a light pipe. The light pipe has an incident surface at an illuminating end of the light emitting element and an ejected surface adjacent to a sensing platform of a sensing system. The sensing system includes a light collection device and a sensing platform for disposing a testing object. The light collection device includes an aperture stop for adjusting the shape of a light spot on a color sensor to avoid glare, a light collection lens set for detecting and projecting an image of a testing object on the sensing platform onto a field stop, a field stop for separating a light from an area other than the effective sensing area of the sensing platform, an uniform lens set for spreading the image on the field stop over the whole color sensor, and a color sensor for capturing and analyzing the color to adjust the brightness and chroma and output an analysis signal.

    Abstract: The apparatus and methods herein provide quantitatively controllable light sources and expanded dynamic range endoscopy systems that can improve the quality of images and the ability of users to distinguish desired features when viewing tissues by providing methods and apparatus that improve the dynamic range of images from endoscopes, in particular for example with endoscopes that have dynamic range limited because of small image sensors and small pixel electron well capacity, and other optical system constraints. The apparatus and methods herein, for example, combine light sources with quantitatively variable spectral output and quantitatively variable wavelength dependent intensity distribution with image sensors and controllers to create an expanded dynamic range endoscopy system. By digitally combining illumination data from the digitally controllable light source with the digital image data from the image sensor the system synthesizes expanded dynamic range images whose dynamic range exceeds the dynamic range of the image sensor alone thus providing greatly enhanced information content in the acquired images.
