Embodiment Construction

[0030] The technical features of the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0031] figure 1 Shown is the measurement principle diagram of the embodiment of the present invention. Including detecting light source, detector, observing background light source, placing the detection object between the detection light source and the detector, performing multiple sampling measurements in sub-bands, and the results obtained are integrated, weighted, and finally displayed. When measuring in sub-bands, multiple bandpass filters of different bands or light sources of different bands can be used. In practice, the visible light range of the human eye is considered, and the sampling and integral calculation are only performed in the range of 380~700nm. In this embodiment, multiple band-pass filters of different bands are used for sub-band measurement. After the detection light source passes through the detection ...

Abstract

The present invention relates to a transmission density detection method, and discloses a detection method for a transmission density close to a human eye sense organ. According to the detection method, a detection light source, a detector and an observation background light source are provided, a detection object is placed between the detection light source and the detector through carrying out detector correction and human eye sensing correction on the detection light source to carry out a plurality of sampling measurements in wave bands, and the obtained results are subjected to integration and weighting. Compared with the existing measurement method, the detection method of the present invention has the following advantage that: the transmission density close to a human eye sense organ can be obtained.

Description

technical field [0001] The invention relates to a transmission density detection method, in particular to a transmission density detection method closer to the sense of human eyes. Background technique [0002] In the prior art, someone proposes visual density, and discloses a measurement method of human eye spectral visual efficiency: ,in , is the spectral energy distribution of the light source, is the spectral luminous efficiency, is the spectral transmittance. This method is the closest prior art. [0003] Since the spectral distribution of the observed background light source is different from that of the detected light source, the detection method in the prior art obtains the transmission density under the detected light source instead of the observed transmission density under the background light source, and there is an inevitable difference between the two. The above detection method does not take into account that the induction curves are different u...
