    Abstract: Micro-lenses (3a and 3b) are formed on the first surface of a transparent substrate and an outgoing efficiency control device (2) for modulating quantity of incident light is disposed on the second surface opposite to the first surface. Incident light (4) is allowed to be incident obliquely with respect to the optical axis of the micro-lens (3a) and is condensed on the outgoing efficiency control device (2). The outgoing efficiency control device (2) modulates quantity of light of incident light and outputs it as outgoing light (5). This construction can make the size of the outgoing efficiency control device (2) smaller than the beam diameter and the aperture of the micro-lenses.

    Abstract: To calibrate a photodetector, a rotating disk with a slot is disposed in a light beam with decreasing speed from a defined maximum rotational speed to a defined minimum speed, while magnitudes and times of signals are read out and stored. Vernier pairs of signals occur in adjacent readout intervals, and non-vernier signals exclude the verniers. Readout times for verniers are used to estimate a preliminary function of rotations versus time. From the function are estimated an occurrence time for each pair and period of disk rotation at the time. Vernier fraction is the ratio of one signal in the pair to the sum of the pair. A time offset is the product of vernier fraction, slot fraction of the disk and the estimated period. Occurrence times corrected with the time offset are utilized to fit a corrected function of disk rotations versus time. Points of time for the non-vernier signals are determined from the corrected function, each point corresponding to disk rotations to a corresponding non-vernier signal. These points of time are employed with corresponding signals for linearly calibrating the photodetector.

    Abstract: A calibration system for periodically calibrating an optical instrument on board a satellite with reference light. In the disclosed system, a calibration unit has two photodetectors one of which is positioned near the light source which radiates reference light and the other near the aperture from which the reference light emerges toward optics of the instrument. Therefore, it is possible to discriminate between contamination or degradation of the optical instrument and contamination of the calibration unit. Two identical and independent calibration units are employed to provide redundancy and enhance the accuracy of calibration.

    Abstract: A radiometer mounted on an aircraft, satellite or similar flying body for observing reflections or radiations of visible rays or infrared rays from the land or the sea. The radiometer has optical means for receiving and converging the visible rays or infrared rays, light-sensitive elements to which the converged rays are incident, means for changing the optical distance between the light-sensitive elements and the optical means, and means for generating correction data while the focal distance of the optical means is deviated from the light-sensitive surface of the light-sensitive elements.

    Abstract: Color calibration for digital pathology is provided. A standard glass slide is prepared with a specimen having zero or more stains. The specimen is scanned a first time using a hyperspectral imaging system to produce a first digital image having XYZ color values. The specimen is scanned a second time using a digital pathology imaging system to produce a second digital image having RGB color values. The first and second digital images are then registered against each other to align the digital image data. Individual pixels of the first and second images may be combined in the registration process so that the first and second digital images have substantially similar pixel sizes. A lookup table is generated to associate XYZ color values to RGB color values. Once the lookup table has been generated, it can be used to present RGB color on a display using the corresponding XYZ color.
