Laser torch schematic
The laser torch is an economical device with impressive cost-performance characteristics. Its primary feature is the exceptional performance of the condenser, allowing for an optical range of 1200 to 1500 meters. The beam remains focused and small even at distances...
Laser Track Detection
The following diagram shows the basic laser pointer circuit. It is identical to the infrared circuit except that the infrared LEDs have been replaced by the laser pointer unit. Due to the long range of these devices, this detector method...
Electronic Transformers Modulation
Wave-filter principles are utilized in various circuits beyond filters, such as in the design of modulation transformers for high-level amplitude-modulated radio transmitters. Some of these transformers are quite large. In plate-modulated power amplifiers, the modulator power necessary for achieving 100...
3D Laser Scanner
The red laser line gradually sweeps across the object, which in this case is a Fabuland lamb head. Behind the scanned object, two planes positioned at a 90° angle provide a reference for the scanning software. These planes are marked...
Optical-pick-up-tachometer
The purpose of this simple circuit is to enable remote, non-contact measurement of the speed of rotating objects. The circuit exhibits high linearity and accuracy, typically constrained by the milliammeter utilized and the initial calibration process. It is configured to...
modulation is process of changing
Modulation is the process of altering certain characteristics (such as amplitude, frequency, or phase) of a carrier wave in accordance with the intensity of the signal. The provided figure illustrates the electronic circuit of a simple amplitude modulation (AM) modulator....
