Light of two wavelengths is passed through the patient to a photodetector.

The sphere was nearly buried behind photodetector leads and lenses.

There were loops for the hours and for the minutes, each one read with a photodetector.

A photodetector picked up messages it was tuned to.

These are generally based on a laser diode with a built-in photodetector.

The reflected probe light is input to a high bandwidth photodetector.

The photodetector's output runs through an amplifier and drives a speaker.

The guiding laser is reflected off of the mirror and detected by a photodetector.

The Crab is designed to avoid bright lights and hide in dark spots by way of a photodetector.

An electric eye is a photodetector used for detecting obstruction of a light beam.

This reaction also produces light (chemiluminescence), which can be measured with a photodetector.

Readers who are interested in the applications of photodetection processes may want to read photodetector.

Intel says it has made further progress in developing a silicon-based avalanche photodetector.

As particles pass through the fringes, the Doppler-shifted light is collected into the photodetector.

This change is detected and converted to an electric signal by a custom-built photodetector.

One sort of photodetector, the photoresistor, has a resistance which varies with illumination.

Instead, a photodetector is placed in the path of the transmitted half of the entangled state.

A lamp shines through one side of the strip and hits a photodetector on the other side.

The current generated by a photodetector generates photo voltage, but in a nonlinear fashion.

Winston cones are used to concentrate light from a large area onto a smaller photodetector or photomultiplier.

In the specific case of a photodetector, responsivity measures the electrical output per optical input.

After striking the surface, the polarized beam is reflected back to a photodetector, which converts the variations into data.

Such mirrors darken automatically when bright lights hit a photodetector, which sends a current to the mirror.

A single photodetector behind the disk captured the image brightness at any given spot, which was converted into a radio signal and broadcast.

At each end, the single photon was offered two choices-a long path and a short path to a photodetector.
