|
|
Laser Beam Alarm - (electronic circuit added 11/06) |
|
Laser Beam Printer LBP Controller Solution Card - National Semiconductor
Application Note.....[App Note] |
|
Laser Communication System - This is a simple Laser communication system. It can
transmit and receive signal from any audio device.Communication distance is few meters.
All components are not critical. Transistor 2N2222 may be on the coolrib. Laser diode is
from laser pointer.....(electronic design added 6/07) |
|
Laser communication via serial Port & more? - Lately I have been daydreaming a
lot in my laser communication course. Surfing around Google after class, I managed to find
an article on sending serial port data over a laser link. The article is rather old
(1997), but was published in a prominent Australian magazine. This is way back when
a good, red laser pointer was only $70..... |

Laser Communicator #2 - (electronic circuit added 7/03) |
|
Laser diode driver circuit - Schematic only, no circuit description |
|
Laser diode transmitter - Schematic only, no circuit description |
|
Laser Head 1.0 - 74AC86-based solar head; lights a high-intensity LED when
locked on a bright light. (added 6/06) |
|
Laser high-voltage power supply - (circuit added 1/07) |
|
Laser Link Communicator - audio transmission up to few hundred meters (circuit
add 04/03/02) |
|
Laser Pointer Train Detector - This train detector makes use of hand held laser
pointer devices that are widely available to detect trains over long distances. [from Rob
Paisley's Model Train web site] |
|
Laser power supply (Aaron Cake) - (electronic circuit added 7/03) |
|
Laser Printer - Intersil Application Block Diagram.....[App Note] |
|
Laser range finder & reflectivity meter for the MARS-96 international space project -
(electronic circuit added 2/07) |
|
Laser simulator helps avoid destroyed diodes - 6-Jan-05 Issue of EDN Laser
diodes can destroy themselves in a few nanoseconds, so testing the response and stability
of a feedback-stabilized laser-diode driver can be expensive. The simulator circuit in
Figure 1 shows a typical laser-diode package, which contains not only the diode, which is
driven by current IL, but also a photodiode..... [Design Idea by Nick Cornford,
Berkhamsted, Hertfordshire, UK] |
|
Laser Target Finder Sensor - (electronic circuit added 1/07) |
|
Laser Torch-Based Voice Transmitter & Receiver - ..... |
|
LASER Transmitter/Receiver - ….(electronic schematic added 08/08) [Site is under
construction right now] |
|
Laser transmitter/receiver (Aaron Cake) - This set of two circuits from the
basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed
at a receiver that demodulates the signal and then presents the information (voice, data,
etc..). The whole thing is very easy to build and requires no specialized parts execpt for
the LASER itself(electronic circuit added 7/03) |
|
Laser Used as Vehicular Traffic Counter - This is an illustration how a laser
could be used to count traffic and measure the speed of each car passing through the
sensor area..... [Designed by David A. Johnson] |
|
Laser/LED Light Output Intensity Meter - This circuit uses a large 1cm X 1cm
silicon PIN photo diode and a transimpedance amplifier to measure the light power output
of infrared and visible LEDs and laser diodes. It can be modified to produce almost any
milliwatts to volts scale factor. It can be connected to either a multi-meter or an
oscilloscope. …. [Designed by David A. Johnson] |

Laser-Diode Driver Stabilizes Sensitivity Parameters - 11/05/98 EDN-Design
Ideas.....The conventional advantages of lasers—coherence, monochromaticity, and extreme
compactness—make laser diodes popular in most of their potential applications. Biomedical
diagnostics and high-resolution-spectroscopy applications exploit laser diodes' wavelength
tunability. These applications use the laser wavelength's sensitivity to drive current and
operating temperature—0.025 nm..... [Design Idea by Anil Kumar Maini and Nita Sen, Defence
Science Centre, Delhi, India] |
