Detection of optical and infrared radiation

Plasmonically enhanced thermomechanical detection of infrared radiation.

Nanoplasmonics has been an attractive area of research due to its ability to localize and manipulate freely propagating radiation on the nanometer scale for strong light-matter interactions. Meanwhile, nanomechanics has set records in the sensing of mass, force, and displacement. In this work, we report efficient coupling between infrared radiation and nanomechanical resonators through nanoante...

Remote Detection of Cat by Infrared Radiation

Several years ago, it was established by the work of P. W. Kadlec of Eastern Airlines (Project TRAPCAT, Ref. 1), that clear air turbulence was frequently associated with temperature gradients or discontinuities in the atmosphere. Barnes Engineering Company had just completed the development of the Satellite Infrared Spectrometer (SIRS) for the Weather Bureau for remote atmospheric temperature p...

Infrared Radiation Detection Using Fiber Bragg Grating

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Refractive Dual Band Infrared Imager Optical Design

Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...
