The development of infrared viewer / Shamzuraili Mamat

This report describes the development of an infrared viewer. An infrared viewer is an electro-optical instrument used for direct viewing of infrared. Among the numerous applications are disceming infrared emissions, reveaüng invisible marking and seeing in the dark. It consists of power supply, Cockroft-Walton and image converter tube. A 6 V d.c supply is used to activate the HV transformer in the power section. Besides, divider circuit was employed to stabilise the output from Cockroft-Walton. The major components of an infrared viewer are built-in invisible infrared source, 'T' mounts lens for viewing the infrared, a 6032 image converter tube for transforming invisible picture to visible picture and an eye piece for viewing the visible picture Various testing has been conducted at various critical points to ensure the required performance and output such as testing on each of the Cockrof-Walton stage, flyback transformer and variable resistors. Due to unavailability of single exact value component a number of components were connected in series or parallel, wherever appropriate, in order to achieve the highest possible output
