  • Publication number: 20040002644
    Abstract: This invention relates to a method, device and apparatus for digitizing electromagnetic radiation measurements by control of camera shutter speed. The invention uses an Electromagnetic Radiation Sensitive Device (ERSD), such as for example a camera system containing a CMOS- or a CCD-image chip, to perform precise measurements by high-resolution digital control of the shutter speed. A constant output value is obtained from the ERSD such that any non-linearity and range limitation of the ERSD output is circumvented. The measurement methods and system are applied to chemical tests and analytes, which are used for diagnostic purposes. The method can be used to measure reflectance, transmittance, fluorescence and turbidity.

  • Publication number: 20030048375
    Abstract: A system for digitizing light measurements controls the emission of a light source illuminating an illumination region to obtain a constant or near constant signal from a light sensitive device. A light source controllably illuminates an illumination region having a test object using a plurality of light signals. A light sensitive device records the plurality of light signals generally modified by the test object in the illumination region and transmits an output signal corresponding to the modified plurality of light signals. A data processor system receives the output signal and generates a control signal. A light source controller is coupled to the data processor system via the control signal. The light source controller controls the operation of the light source, whereby the emitted light signals are adjustably controllable such that the output signal is constant.
