Abstract [en]

The task for this master thesis was to create a specification for a second prototype of Scandilumen´s handheld gated night vision system. Current prototype is analogue and is to be upgraded with a digital interface. The specification was to contain information about manufacturers and performance on critical components such as image intensifier tube, image sensor and display. Scandilumen have previous experience with CCD cameras and wanted to know if the CMOS technology were sensitive enough to work properly in gated systems where high sensitivity is critical. Different image processing techniques was analyzed to find out the possibility to enhance image quality with an FPGA built-in into the system. When the specification is implemented, Scandilumen will have a prototype up-to-date with a digital interface and real time image enhancement.

Abstract [sv]

Uppdraget i denna magisteruppsats var att ta fram en specifikation för en andra prototyp av Scandilumens grindade mörkerkamera. Nuvarande prototyp är analog och skall uppgraderas till en digital variant med display och anslutningsmöjlighet till dator. Specifikationen skall innehålla uppgifter om vilka ingående komponenter som skall användas samt vilken prestanda de skall ha. Exempel på dessa komponenter är bildförstärkarrör, bildsensor och displayer. Stor vikt har lagts vid att avgöra vilken typ av bildsensor som skall ingå i systemet. Scandilumen har tidigare erfarenhet av CCD-kameror men ville undersöka om CMOS-tekniken var känslig nog för denna typ av applikation. En jämförelse gjordes mellan de olika teknikerna med fokus på de höga krav som ställs på känslighet. Dessutom analyserades olika typer av bildbehandling som är lämpliga för systemet och som också går att implementera i en FPGA på lämpligt sätt. Om specifikationen följs kommer Scandilumen ha en prototyp uppdaterad med ett digitalt format och den senaste tekniken.
