Multiple optical detectors continuously monitor the sample for movement.

It will then have one or more optical detectors that can detect at the wavelength that the dye fluoresces at.

An array of optical detectors continuously monitor the sample for the first appearance of a cloud of wax crystals.

Starting in the 1940s, there was much scientific interest in classifying the signal and noise performance of various optical detectors such as television cameras and photoconductive devices.

Others use optical detectors, which seem to respond more quickly to smoke from smouldering fires such as those involving upholstered furniture.

It is a law, which is valid for all optical detectors.

An optical detector is a light sensor.

A vacuum cleaner can be used to clean ionization and optical detectors externally and internally.

It was a plywood box with sheets of webbed steel that sheltered the optical and microwave detectors from outside emissions.

Diffraction effects limit the ability for an optical detector to optically resolve separate light sources.
