Photometric system

Abstract

The invention provides a photometric system. The photometric system comprises a laser ranging module, an illumination measuring module and a data processing module; the laser ranging module is used for measuring the distance between a light source and the system and transmitting the generated distance data to the data processing module; the illumination measuring module is used for measuring the illumination of light generated by the light source and transmitted to the system and transmitting the generated illumination data to the data processing module; the data processing module is used for calculating the received distance data and illumination data to obtain the illumination intensity data of the position of the system. The laser ranging module and the illumination measuring module measure the distance and illumination synchronously, so that the illumination data and the distance data can be obtained at the same time and at the same place to the maximum, the accuracy rate for measuring data and the working efficiency can be improved, and the inconvenience of switching the devices manually is avoided while a photometer and a diastimeter are sequentially adopted for measuring.

Description

technical field [0001] The invention relates to the technical field of photometry, in particular to a photometry system. Background technique [0002] At present, the existing light intensity measurement method is to measure light intensity with a photometer and a rangefinder separately, so as to obtain standardized light intensity data. Specifically, after measuring the light intensity data emitted by a single light source, measure the distance with a distance meter at the same position where the light intensity data is measured, and finally use the two data to calculate on the calculator to get the final result. [0003] However, the above-mentioned method of measuring light intensity has many disadvantages: first, hand-held measurement will inevitably have displacement errors when replacing measuring equipment, and the attenuation of light is more sensitive to distance changes, specifically, it is attenuated according to the square of the distance , therefore, the displa...
