    Abstract: This invention integrates a spectrometer capability with the basic imagery function of facsimile cameras without significantly increasing mechanical or optical complexity, or interfering with the imaging function. The invention consists of a group of photodetectors arranged in a linear array in the focal plane of the fascimile camera with a separate narrow band interference filter centered over each photodetector. The interference filter photodetector array is on a line in the focal plane of the facsimile camera along the direction of image motion due to the rotation of the facsimile camera''s vertical mirror. As the image of the picture element of interest travels down the interference filter photodetector array, the photodetector outputs are synchronously selected and sampled to provide spectral information on the single picture element. The selection of the proper photodetector and data sampling is controlled by information derived from the servo system controlling the vertical mirror rotation.

    Abstract: An instrument for determining optical density by measurement of diffuse reflected light. The instrument includes a light source, means for forming a beam of diffuse reflected light, an electrical balancing circuit, and an optical attenuator for controlling the intensity of light incident on a photoresponsive element forming a part of the balancing circuit. In the use of the instrument, the units of optical density are read directly from the optical attenuator, and mechanical movement thereof serves to provide an aperture of increased or decreased size, admitting more or less light, until electrical balance is achieved in the circuit. A balanced circuit condition is indicated by extinguishment of a single bulb, and the reading is taken only when the balanced condition occurs. In the preferred form of construction, the optical attenuator is in the form of a disc or wheel having a gradually increasing opening therein, and adapted for direct manipulation by the operator. Calibration of the instrument is achieved by illuminating a standard or known control specimen, and adjusting a nulling potentiometer in a balancing bridge to produce a balanced condition in the circuit. By using a mechanical attenuator instead of an electrical signal strength control, the unit is simplified in construction and is more accurate and reliable in use.

    Abstract: A blood testing system which includes a colorimeter for observing the light transmission characteristics of a reacted blood sample to determine the concentration of a particular component. The colorimeter includes a lamp, a sample holding well, a photocell, and a meter having a needle to indicate the output of the photocell. A removable module is provided which is adapted to plug into the circuitry of the instrument and adjustably calibrate the instrument for a particular blood determination. The module includes a printed scale which is designed to be positioned immediately adjacent the meter needle when the module is operatively connected to the colorimeter, the units of the scale being correlated to the particular blood determination of the module such that the scale reads directly in the units of the test being conducted. By employing a number of modules, each being color-coded and calibrated for a particular blood determination, the colorimeter may be easily adapted to perform a number of tests by merely inserting the appropriate module. A carousel is provided for mounting several modules in the instrument, the carousel being rotatable to sequentially translate individual modules to the operative position adjacent the output needle of the meter. A number of filters are provided for the colorimeter, and a mechanism is incorporated which is designed to selectively position individual filters in the light path of the colorimeter. A patient record card is provided which is adapted to overlie and be temporarily affixed to the module. The card, which may also be color-coded, includes a scale which overlies the scale of the module, this scale being adapted to be marked to serve as a permanent record of the test determination. A removable tear-off tab is associated with the card which may be utilized to identify a blood sample by patient number and test. A number of marked cards, obtained over a period of time for a particular test, is adapted to be placed in overlapping relationship whereby the test results will be displayed as a graph plotted against time. A folder is provided to retain the cards in such overlapping relationship, the folder having a clear plastic overlay with indicia thereon to indicate the normal range of the test results. The cuvette containing the reagent required for the blood determination is provided with a molded plastic cap which is designed to retain a capillary within the cuvette when the cap is attached. For this purpose, the cap includes an integral depending flap having an aperture therethrough, the aperture being designed to threadedly receive the capillary.

    Abstract: An instrument for the instantaneous measurement of the chromaticity of time variant spectral sources including a plurality of narrow band sensors or transducers that in combination encompass the visible spectrum. Each consists of an interference filter and a linear photovoltaic cell whose three output voltages have been ''''optimum multiplied'''' for the three tristimulus functions through a voltage divider network. The corresponding individual outputs of the sensors are added by a summing feedback amplifier to provide a voltage output proportional to the tristimulus values. These proportional outputs are then summed by a unity gain summing amplifier whose output in turn is applied to one input of a pair of ratio recorders. The other ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder output, therefore, is one of the normalized chromaticity coordinates. The output coordinate values (x and y) are simultaneously fed into a chart recorder to derive a plot of the chromaticity coordinates vs. time. The invention described herein may be manufactured, used and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon.

    Abstract: An optical magnifying lens is mounted as part of a manually portable color printing analysis device which has support means adapted to position the lens properly above a color print surface to be inspected. A light on the device illuminates the surface, and a color filter is mounted for selective movement into the field between the lens and surface. The filter color is complementary to the color of that part of the surface to be checked. For example, a blue filter is provided for inspection of yellow printed surfaces. Preferably one or more such color filters are mounted on a filter plate movably supported on a body portion of the device, which body portion also serves as a handle and battery case. Inspection of the surface through the magnifying lens and filter provides an enlarged dark contrast image of the desired color printed areas, such as the colored dot portion of a colored halftone sheet, even though some of the colors to be inspected are partially overprinted by other colors.
