Development of an Optical Smart Portable Instrument for Fruit Quality Detection
IEEE Transactions on Instrumentation and Measurement, 2021In this study, a portable optical instrument was designed and developed for real-time nondestructive determination of fruit ripeness. A prototype of the instrument using inexpensive parts was developed and calibrated for apple ripeness detection based on

Space optical instrument for GEO-Ground laser communications
International Conference on Space Optics, 2023In the framework of the TELEO demonstration, a space optical instrument is being developed by a European consortium led by Airbus at Toulouse. This laser communications terminal will be placed on GEO orbit during the year 2023. Our flight laboratory will

Optics and Optical Instruments
American Journal of Physics, 1961By B. K. Johnson New Tork: Dover Publications Inc. London: Constable & Co. Pp. viii + 224. Price $1.65. This book is an unaltered republication under a new title of the second (1947) edition of the author's Practical Optics. It is difficult to see why the title has been changed; this is a practical handbook which might appeal most to amateurs or to ...

Optical Instrument for Thickness Measurement
2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020In modern metrology it is increasingly common to find the importance of thickness measurements in the production processes of compact materials (metals, plastics, paper, rubber, etc.). A quick and timely measurement is indispensable in those automated industrial processes capable of modifying the production parameters in real time in order to have the ...

On Perfect Optical Instruments
Proceedings of the Physical Society, 1948The angular characteristic function T is used to investigate optical systems of finite focal length in which one extended surface is imaged on another without aberration. The forms of T found earlier to correspond to perfect imagery are shown to be exhaustive. When perfect imagery is achieved the image surface is similar to the object surface, with the
