AI Thread Summary
When selecting an optical chopper system, the chopping frequency significantly impacts the application. Chopping at different frequencies, such as 500Hz versus 900Hz, primarily affects the modulation of the beam and its interaction with the material being tested. Higher frequencies may provide finer control and better resolution in certain applications, while lower frequencies might be sufficient for others. Ultimately, the choice should align with the specific requirements of the intended use. Understanding these differences is crucial for optimizing performance in your work.

hi friends
I am going to buy optical chopper system for my work. But i need some clarification about system. If i want to chop say 2mm diameter of the beam, say it has of chopping frequency from 500Hz to 1000Hz. What is the difference if i chop at 500Hz and 900 Hz except the frequency.

Thank you for advance wishes

Regards

Note the bold in your question that I added for emphasis. The chopping frequency is variable and can be set to any value in the range given. It's up to you depending on your application.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
