Embodiment 1
[0097] In this embodiment, a mobile phone small flashlight is used to detect the light transmittance of the sample to be tested. The steps of the detection method are as follows:
[0098] (1) Fix a dark environment, fix a detection box, put the mobile phone into the detection box, the direction of the small flashlight of the mobile phone is upward, and the reading of the illuminance meter in the detection box must be ≤5Lux. The test box is empty, only the light meter and mobile phone.
[0099] (2) Measure unobstructed readings: Manually move the photometric head of the illuminance meter so that the vertical tangent point of the receiver is close to the small flashlight of the mobile phone and move slowly for a few circles, take the maximum value of the illuminance meter reading, and record the reading as the unobstructed reading.
[0100] (3) Measure the occlusion reading: put the sample to be tested on the small flashlight of the mobile phone, move the position of the cake, e...
Embodiment 2
[0107]The difference between this embodiment and embodiment 1 lies in that: a flashlight with a stable light source is used instead of a small torch of a mobile phone to detect the light transmittance of the sample to be tested, and the measurement method is the same as that of embodiment 1. Table (2) is the relevant data obtained by measuring the same thickness measurement point in the same sample to be tested at different time periods using the same fully charged flashlight in the same test box and under the same ambient light.
[0108]
[0109] Table 2)
[0110] The method of the present embodiment is the measurement method that the prior art often adopts, as can be seen from table (2), for the same sample to be tested, in other factors (illumination environment, sample thickness, material contamination degree, hand shake situation) Under the same circumstances, the measured light transmittance is still different from each other when using a flashlight with a theoretical...
Embodiment 3
[0112] In this embodiment, detection boxes with different ambient illuminances are used for measurement. Except that the ambient illuminance of the detection boxes is different, other detection conditions are the same, and the samples to be tested are placed on a sample stage and fixed by a detection fixing table. The illuminance meter replaces the manual operation of the illuminance meter. Table (3) is the relevant data obtained from the measurement.
[0113]
[0114] table 3)
[0115] It can be seen from Table (3) that the ambient light intensity in the test box directly affects the reading of the illuminance meter that blocks the light source. This is because, according to the working principle of the illuminance meter, the receiver does not selectively receive the light intensity, but only measures the illuminance of the real-time environment. Therefore, the ambient light intensity in the detection box directly affects the reading of the illuminance meter that blocks th...
