Celluloide Film Based Infrared Bandpass Filter for Thermography

Abstract:

A commercial digital camera was employed for thermal imaging. To do so, an infrared filter was required to block the light except the infrared part of it. The filter was developed using a celluloide colour film burned by certaint intensity of light. In this reseach intensity of monochromatics as well as polychromatics light of 1.00, 1.50, 2.70, 4.00, 8.00, 12.00, 16.00, 24.00, 30.0 and 40.00 klux have been used. The infrared filter produced then characterised their light transmitance using a spectrophotometer. Images of a light bulb and a hot iron plate were taken in a dark room using a digital camera equiped with and without infrared filter. The results show that the infrared filter produced from a celluloide colour film burned by a monochromatics light at intensity of 1.00 klux has the best permomance.
