Portable monitoring devices are widely used by people from different sectors of the society and their use is steadily increasing. Health monitoring and environmental monitoring have drawn the attention of many personnel as key monitoring areas that need major improvements. Targeting these advances, infrared (IR) technology has used to develop the imaging – type two – dimensional Fourier spectroscopy which has incredibly high potential to succeed in both areas. Imaging – type two – dimensional Fourier spectroscopy is a simple optical configuration which used IR as input light source, a camera as the detecting device, a variable phase filter as phase changer, and few more lenses. First, sample is illuminated using light source and reflected or transmitted lights send through a lens called objective lens. Then, these lights are directed to the phase filter which has movable part and stationary part. Using this, part of the incident lights are delayed before sending to a camera through lens called imaging lens. The camera collects lights which have different intensities. Finally, absorbed wavelengths of light can be found using Fourier Transform and they can be used to calculate measurements. In health monitoring, blood glucose measurement and hemoglobin testing are main targeted areas. Since the proposed system is non-invasive, it is pain-free method. Initially system was tested with biogenic substances obtained from mouse ear and then experiments were carried out for glucose measurement at laboratory conditions. This device will release painful experience of blood glucose measurement by millions of diabetic patients.
