Latest Patents

Chang Yong's latest patents include a compact apparatus for high-speed chemical spectral signature measurement. This multiband IR adjunct (MIRA) sensor is designed to spectroscopically determine the content and concentration of chemical compositions in targeted objects. The apparatus features a sensor housing, front optics in an optical channel, an acousto-optic tunable filter (AOTF), and a photo detector (PD). The PD converts polarized narrow-band light beams into electrical signals, which are then collected by a data acquisition unit. The design allows for multiple optical channels to analyze various wavelength ranges, including UV/VIS/near infrared (NIR), short-wavelength infrared (SWIR), mid-wavelength infrared (MWIR), and long-wavelength infrared (LWIR).
