摘要： Method and apparatus for forming grey-scale images on a photosensitive imaging medium, the medium being capable of spatial resolution finer than pixel dimensions of the exposing apparatus. The medium is exposed to a pixellated array of exposure sources which may be liquid crystal shutters or light emitting diodes. A transmission density is developed in imaged areas that varies non-linearly with the exposure energy received by the imaged areas in which the exposure conditions are adjusted such that the variation in average transmission over a whole pixel area from image pixel to image pixel caused by spatial energy distribution variations is less than 5% for the same energy delivered to each pixel area. The pixellated array of energy sources may be two rows of exposure pixels in a parallel but staggered configuration and associated with a SELFOC lens array, each of the exposure pixels having a light-emitting area, in which light-emitting areas of one of the two rows are substantially the same size and shape as gaps between light-emitting areas of the other of the two rows. The pixellated array may also be a single row of exposure pixels associated with an array of microlenses and the SELFOC lens array, arranged so that the expression:a/2-f tanis greater than zero, where f=focal length of a microlens, a=width of an exposure pixel, and =acceptance angle of the SELFOC lens array.

摘要： A biological growth plate scanner includes a multi-color illumination system that illuminates a biological growth plate with different illumination colors. A monochromatic image capture device captures images of the biological growth plate during illumination of the growth plate with each of the illumination colors. A processor combines the images to form a composite multi-color image, and/or individual components of the composite image, and analyzes the composite image to produce an analytical result such as a colony count or a presence/absence result. The biological growth plate scanner may include both front and back illumination components. The back illumination component may include a diffuser element disposed under the biological growth plate. The diffuser element receives light from one or more laterally disposed illumination sources, and distributes the light to illuminate a back side of the biological growth plate. The illumination sources in the front and back illumination components may take the form of sets of light emitting diodes (LEDs) that can be independently controlled by the processor.

摘要： An optical fiber having a core is disclosed. A notch having first and second sides is formed in the fiber and extends into the core. At least the portion of the interior of the notch adjacent the first side has an index of refraction less than that of the core. Light travelling at a first angle to the fiber axis and striking the first side will be totally internally reflected if the first angle is greater than a predetermined angle. If the first angle is less than the predetermined angle, a portion of the light will enter the notch and emerge through the second surface making a second angle to the first surface, the second angle being greater than the first.

摘要： Apparatus and imaging method in which an LED exposure apparatus having an array of light emitting diodes stationed in a light exposing relationship to a photosensitive material to be imaged is calibrated to take into account the wavelength difference between light emitting diode emissions and the spectral sensitivity of the photosensitive medium. The exposure apparatus is calibrated by making separate energy measurements of each light emitting diode with a detector through a colored filter. The spectral response of the detector and filter combination matches that of the photosensitive material in the wavelength region of the emission of the light emitting diode. The energy measurement are used to modulate each exposure level of the array of light emitting diodes. The calibration method is used during exposure of the photosensitive material by the array of light emitting diodes, particularly for grey scale imaging. The detector and filter are used to modulate exposure in response to the energy measurements.
