What is Photometry?

Photometry Definition

Photometry is defined as the science of measuring light in terms of its perceived brightness to the human eye.

Fiber Photometry

Fiber photometry uses optical fibers and fluorescent indicators to record neural activity in living animals.

Flame Photometry

Flame photometry determines the concentration of metal ions in a sample by measuring emitted light from a flame.

Reflectance Photometry

Reflectance photometry measures the color and reflectance properties of surfaces by analyzing reflected light.

Photometric measurement and method

Photometers
Colorimeters
Integrating spheres
Goniophotometers
Photodetectors

Photometric Applications

Photometry is used in various fields, including astronomy, lighting, vision, chemistry, biology, and art, to measure and understand light.

Battery charging process using AC adapter

Battery charging process using AC adapter

The process of charging the battery using the AC adapter is as followsConnecting devicePlug the AC adapter into the power outlet, making sure the connection is secure and stable. At this point, the AC adapter starts to obtain AC power from the grid.Connect the output of the AC adapter to the device that needs to be charged, usually through a specific charging interface or data cable.Ac adapter operationInput AC conversionThe circuit inside the AC adapter first rectifies the input AC power, conve

The circuit working principle of one-way switch

The circuit working principle of one-way switch

A one-way switch is the most basic type of switch that has only one input (often called the "normally on" or "normally closed" state) and one output. The working principle of the one-way switch is relatively simple, but it has a wide range of applications in various electrical and electronic devices. The following details the circuit working principle of the one-way switch:The basic structure of a one-way switchA one-way switch usually consists of the following parts: Contact: A metal part used

What is the effect of applying alternating current to a DC machine?

What is the effect of applying alternating current to a DC machine?

Applying alternating current to a DC motor can have a variety of adverse effects because DC motors are designed and operate to handle direct current. The following are the possible effects of applying AC to a DC motor:Cannot start and run properly No natural zero crossing: AC has no natural zero crossing to help the motor start, while DC motors rely on constant direct current to establish a magnetic field and start. Inversion phenomenon: The sinusoidal waveform of alternating current changes dir
