How Do Electronic Cameras Use IR to Measure the Distance to the Subject

Electronic cameras often use infrared (IR) technology, specifically Time-of-Flight (ToF) or Active IR methods, to measure the distance to the subject. Here’s how each method works: 1.Time-of-Flight (ToF): (1)Time-of-Flight cameras emit short bursts of infrared light pulses towards the subject. These pulses bounce off the subject and return to the camera’s sensor. By measuring the …

What are Millicandelas

Millicandelas (mCd) are a unit of luminous intensity commonly used to measure the brightness of light sources, including LEDs (Light Emitting Diodes). The term “millicandela” is derived from the standard unit of luminous intensity, the candela (Cd), which represents the luminous intensity emitted in a specific direction by a light source. One millicandela is equal …

Are LEDs more efficient than other light sources such as incandescent and fluorescent types

LEDs (Light Emitting Diodes) are generally more efficient than traditional light sources like incandescent and fluorescent lamps. Here’s why: 1.Energy Efficiency: LEDs convert a higher percentage of electrical energy into visible light compared to incandescent and fluorescent lamps, which waste more energy as heat. This makes LEDs more energy-efficient and helps reduce electricity consumption. 2.Luminous …
