摘要: A method for calibrating irradiance sensors is performed by an irradiance analysis computing device in communication with a memory. The method includes receiving an irradiance estimate representing an expected amount of irradiance, receiving a first irradiance value associated with at least one irradiance sensor, processing the irradiance estimate and the first irradiance value to generate at least one irradiance metric, and determining a condition of said irradiance sensor based at least in part on the at least one irradiance metric.

摘要: A calibration system is provided including an aperture layer, a lens layer, an optical filter, a pixel layer and a regulator. The aperture layer defines a calibration aperture. The lens layer includes a calibration lens substantially axially aligned with the calibration aperture. The optical filter is adjacent the lens layer opposite the aperture layer. The pixel layer is adjacent the optical filter opposite the lens layer and includes a calibration pixel substantially axially aligned with the calibration lens. The calibration pixel detects light power of an illumination source that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source based on a light power detected by the calibration pixel.

摘要: There are provided a drift calculation device capable of accurately calculating a drift by using a buffer of smaller capacity, and a light detection device provided with the same. Every time measurement intensity is input according to a predetermined cycle, data in a plurality of sum buffers 321 to 324 are updated based on at least one of the measurement intensity and the measurement time at that time. The sum buffers 321 to 324 are assigned respectively to a plurality of sum functions forming a coefficient included in a calculation formula for calculating a drift by using the least squares method. A drift is calculated by substituting the updated data in the plurality of sum buffers 321 to 324 in the calculation formula. Since it is not necessary to store all the measurement intensity input at the predetermined cycle, a drift is accurately calculated by a buffer of smaller capacity.

摘要: A temperature compensation circuit for a light source (e.g., light emitting diode (LED)) whose radiant energy output decreases when ambient temperature increases includes a first circuit element for generating a first current that increases proportional to an increase in the ambient temperature, and a second circuit element for generating a second current that is first order independent of the ambient temperature. The circuit further includes a weighted current adder for generating a third current by combining the first and second currents with first and second weights applied to the first and second currents respectively. The circuit further includes a third circuit element responsive to the third current for supplying a fourth current to the light source to maintain a radiant energy output of the light source constant independent of the ambient temperature.
