A device used to measure the intensity of light is called a ___.,本题来源于影视技术英语试题及答案
In use, light, whose intensity is to be measured, falls on to a photo-resistor 1, and the bridge is rebalanced either by adjusting one of its arms, such as resistor 2, or by adjusting a shutter 9 in front of the photo-resistor 1. The lamps could be replaced by light emitting ...
The resistance of the Light Dependent Resistor (LDR) varies according to the amount of light that falls on it. The relationship between the resistance RL and light intensity Lux for a typical LDR isRL=500Lux(1)(1)RL=500Lux If the LDR connected to 5V through a 3.3K resistor, using the...

Light Intensity Light intensity of the LED is a factor of the chip design and material, current level, encapsulation, and other variables. While not particularly important in applications for instrument clusters and other indicators, it is important in lighting applications. The intensity value for ...
aCurrent practice selects ground motions whose intensity (measured by an Intensity Measure or IM) is exceeded with some specified probability at a given site, and whose other properties are also appropriate (as typically determined by probabilistic seismic hazard and deaggregation calculations) 当前...
I need to measure the intensity of the light of different LEDs (red / blue / green / orange). You don't want to adjust the LEDs so they all give the same output from your photodiode and amplifier; you want to adjust their current so the output is scaled according to the photo...
