摘要： A micro-mirror device includes a substrate and a plate spaced from and oriented substantially parallel to the substrate such that the plate and the substrate define a cavity therebetween. A reflective element is interposed between the substrate and the plate, and a liquid having an index of refraction greater than one is disposed in the cavity between at least the reflective element and the plate. As such, the reflective element is adapted to move between a first position and at least one second position.

摘要： An optical system includes a lens, a pupil relay, and an aperture stop positioned at a focal point of the lens between the lens and the pupil relay. The lens is configured to collect a plurality of light bundles. Each light bundle emanates from a field point of an object plane and has a center ray substantially parallel to an optical axis of the lens. The lens is configured to direct the center ray of each light bundle through the aperture stop and onto the pupil relay. The pupil relay is configured to image a plane of the aperture stop onto a sensor array.

摘要： One aspect is a light source assembly in a drop detection arrangement. The light source assembly includes a light source and a gradient-index lens array to at least partially collimate light from the light source and to project a collimated light beam into the drop detection arrangement in a direction transverse to a drop direction of droplets in the drop detection arrangement. The light source assembly produces the light beam such that it has a beam width in a direction transverse to the drop direction that is larger than a beam height in the drop direction.

摘要： In one example, a method for making diagonal openings in photodefinable glass includes exposing part of a body of photodefinable glass to a beam of light oriented diagonally to a surface of the body at an angle of 5° or greater measured with respect to a normal to the surface of the body and removing some or all of the part of the body exposed to the light beam to form a diagonal opening in the body.

摘要： A color measurement device includes a light pipe and a light source. The light pipe is oriented length-wise towards a color sample surface along a first axis that is non-perpendicular to the surface. A color sample is positioned on the surface. The light pipe has a near opening, a far opening, and a face at the far opening. The near opening is closer to the color sample than the far opening. The light source is positioned near the far opening of the light pipe, and is to output light along a second axis and into the light pipe at the far opening. The light reflects off the surface after exiting the light pipe at the near opening. The second axis is non-perpendicular to the face of the light pipe at the far opening. The light non-uniformly illuminates the color sample after exiting the light pipe at the near opening.

摘要： A color detector includes a light source, a first filter, and a first photodetector. The light source generates light within a spectrum of wavelengths. The first filter is in optical communication with the light source and is configured to pass light within a first predetermined spectrum of wavelengths. The first photodetector is in optical communication with the first filter and is configured to output a first color signal if light passes through the first filter. The photodetector has an area configured to equalize the first color signal and maximize a signal-to-noise ratio of the first color signal.
