Theory of Operation
There are four major elements of modules linked to formulate the entire laser system
such as, console, TruScan delivering system, Slit lamp and LCD Touch Screen
integrated with software system.
Console
It is where all the laser beams are generated and distributed. It includes laser diode,
laser cavity, optical platform, microprocessor PCB, and all the electronics controls
circuits. It will interface with the LCD display command. Under the console system, it
contains many subassemblies including: Main PCB, DC/DC PCB, Power Supply, TEC
PCB (depending on type of system), Cavity, Laser Diodes, and Fan Module...etc.
More detailed descriptions are explained in the System Component section.
TruScan Deliver System
There are two high and precision motors and interface PCB located in the housing. It
is where all the different type of patterns are generated through the motor
controlling process.
Slit lamp
It provides illumination to the patience for doctor or user to see clearly. There is
+6VDC and 20W Osram light bulb located inside the tower. More detailed optical
passage is explained in the system components section.
LCD Computer System
It provides the interface between the console and user. This is where all the controls
are located. It is done through the embedded system software.
