Embodiment
With reference to Fig. 1, the present invention is described in further detail.
Refering to Fig. 1, a kind of spectroradio luminance meter, including camera lens 10, spectrometer 20 and industrial control board 30, described camera lens
10 be used to receiving sample send or the light that reflects and by optical fiber output into spectrometer 20, spectrometer 20 is to light
Carry out light-splitting processing to obtain spectral information and spectral information is converted into data signal exporting into industrial control board 30, industrial control board 30 will
Data signal substitutes into the formula of its memory storage and calculate the chromaticity coordinate value for obtaining sample.Pass through camera lens 10, spectrometer 20
Sample is sent or the light progress reflected handles and obtains spectral information, then the formula logarithm by being stored in industrial control board 30
Word signal progress processing can very easily draw the chromaticity coordinate value of sample, and whole process is without manually participating in, full-automatic inspection
Survey, detection speed is very fast, and precision is also very high.Here, the accuracy of detection of spectrometer 20 is higher, then finally calculates
Sample chromaticity coordinate value is also more accurate.
Preferably, the present apparatus also includes control panel 40 and temperature sensor 50, and described temperature sensor 50 is used to gather
Complete machine temperature is simultaneously exported to control panel 40, and control panel 40 is according to the temperature correction function and complete machine temperature of its memory storage to industry control
The sample chromaticity coordinate value that plate 30 is exported is calibrated and is exported the sample chromaticity coordinate value after calibration.Because the present apparatus includes
There is wave length shift and amplitude drift in spectrometer 20, spectrometer 20, have certain relation with temperature and service life in itself, therefore
The present apparatus obtains temperature correction function before integrated by strict high/low temperature test and data acquisition.When measuring sample, lead to
Cross the temperature sensor 50 of setting to gather temperature during present apparatus real work, light can be avoided by carrying out calibration further according to temperature
Spectrometer 20 is affected by temperature brought error, further improves the accuracy of detection.
As the preferred scheme of the present invention, the present apparatus also includes head 60, and described camera lens 10 is fixed on head 60, cloud
Platform 60 is used to adjust the direction of camera lens 10 to realize multiangular measurement.Here camera lens 10 can measure camera lens using wide-angle,
The cooperation of camera lens and head 60 is measured by wide-angle so that measurement angle is more flexible, can be easily from different viewing angles
Luminous or reflected light to testing sample is measured.
Further, the present apparatus also includes compass 70, gyroscope 80 and display 90, and described control panel 40 passes through sieve
Disk 70 monitors the angle of camera lens 10, monitors the gradient of camera lens 10 by gyroscope 80, and control panel 40 inclines the angle of camera lens 10, camera lens 10
Gradient and the chromaticity coordinate value of sample are shown on display 90.Set compass 70 and gyroscope after 80s, in that context it may be convenient to adopt
Collect the angle and gradient residing for camera lens 10；Display 90 is set, facilitates the reading of data.
Specifically, the formula of the memory storage of industrial control board 30 is as follows：
X, Y, Z are the chromaticity coordinate value of sample in formula, are numerical value to be calculated, and φ (λ) is Color Stimulus Function, namely
The light energy of color perception, x are produced into human eye*(λ), y*(λ), z*(λ) is the spectrum of standard colorimetric observer as defined in CIE
Tristimulus values, can table look-up acquisition, and CIE here is International Commission on Illumination.Δ λ spans are 5nm~10nm, wherein,
Δ λ carrys out value depending on spectral characteristic and the computational accuracy requirement of testee, and Δ λ is smaller, as a result more accurate.Generally, Δ λ
When taking 10nm, have been able to provide accurate result；If Δ λ takes 5nm, it is very accurate to provide in most cases
Result.
Specifically, the Color Stimulus Function φ (λ) in above-mentioned formula is that luminous or reflected light has not according to sample
Same calculation：When sample is self-luminous body, φ (λ) is the relative spectral power distributions that luminous object is radiated；It is tested
When object is non-self-luminous object, φ (λ) is calculated according to equation below and obtained：
φ (λ)=τ (λ) * S (λ)
φ (λ)=β (λ) * S (λ)
