PhotoMeter: Easy-to-use MonoGraphoMetrics

MonoGraphoMetrics is the science of computing 3D measures from a single image. Several recent research activities have produced theoretical principles and practical tools for extracting 3D measures from uncalibrated photographs. These tools require that the user identifies configurations of edges, which are used to establish constraints or to identify planes in the scene. The process involved i...

Semiautomatic Twilight Photometer, Design and Working

Aerosol measurements have been carried out at Kolhapur (16.41°N 74.13°E) by using newly designed Semiautomatic Twilight Photometer. Some noticeable features of the semiautomatic twilight photometer are improvement in efficiency of the system, growth in signal to noise ratio, augmentation in height resolution, lot of upgrading in the sensitivity of the system, expansion in duration of operation ...

OPTIMA: A Photon Counting High-Speed Photometer

OPTIMA is a small, versatile high-speed photometer which is primarily intended for time resolved observations of young high energy pulsars at optical wavelengths. The detector system consists of eight fiber fed photon counters based on avalanche photodiodes, a GPS timing receiver, an integrating CCD camera to ensure the correct pointing of the telescope and a computerized control unit. Since Ja...

Automated fluorometer/photometer system for homogeneous immunoassays.

A fully automated bench-top clinical analyzer (OPTIMATE TM; Ames/Gilford) performs homogeneous fluorescent immunoassays, colorimetric immunoassays, and determinations of routine blood analytes; drugs, enzymes, metabolites, specific proteins, and hormones in serum. Unique features include a combination fluorescence/absorbance aspirating thermocuvette, a photon-counting fluorometer/photometer, a ...
