    Abstract: 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.

    Abstract: 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.

    Abstract: A photometer is providing including light detecting means for detecting incident light and generating electric signals in response thereto as a measure of the incident light thereon, and optical means for guiding light to the light detecting means from a standard light source in a calibration mode and from an object, a photometric quantity of which is to be measured, in a measurement mode. Control means are adapted to generate calibration control signals for carrying out a calibration mode wherein a photometric quantity value Dstd of the standard light source and a measured value Rstd corresponding to the intensity of the standard light source detected by the light detecting means are stored in a memory, and light measurement control signals for carrying out a measurement mode wherein a photometric quantity value Rm corresponding to the photometric quantity of the object measured by the light detecting means is also stored in memory such that a CPU or similar computing means can communicate with the memory and compute a photometric quantity value R of the object according to the formulaR=Rm.times.(Dstd/Rstd).

    Abstract: A calibration method comprising, for each of one or more light sensors: (a) under influence of one or more substantially non-zero illumination levels in the target environment, using the light sensor to measure the sensed light level corresponding to each of these one or more illumination levels; (b) receiving a template light level value corresponding to each of the one or more illumination levels, representing the light level at a target location in the target environment substantially removed in space from the location of the light sensor, each of the one or more template light level values being assumed for the environment rather than measured by a light meter; and (c) determining a relationship between the sensed light level and the light level experienced at the target location, based on an evaluation of the one or more sensed levels relative to the one or more template light level values.

    Abstract: 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.
