After undergoing the whole extrusion process history, particles of second-phase upon reaching the optical detector
scatter light and consequently increase the turbidity.
Areas such as eastern Europe, including Russia, have focused most of their optoelectronic research on crystal growth, optical detectors
and the production of lasers.
The optical detector
placed at the slitdie recorded data as a function of time during all time of each extrusion.
The responsivity of two optical detectors
was determined by the method of direct substitution in four different NIST measurement facilities.
Our research group developed an in-line optical detector
that quantifies the turbidity of the system.
One device that can be found in many of these automotive systems is the optical detector
. Climate control, light dimming, laser radar, collision avoidance, blind spot detection and height adjustment are just some of the systems that rely heavily on optical sensors.
Figure 4 shows a schematic diagram of an aperture system for a measurement system consisting of a wavelength selector and an optical detector
(not shown in Fig.
The rear of the contact is ground and polished to accept the optical signal from an edge emitting optical source or to activate an optical detector
. The contact is also an RF conductor by simply lap soldering or wire bonding between the substrate RF conductor and the contact.
These pellets were extruded once more generating a constant response of the optical detector
Li, Spatial Uniformity of Optical Detector
The optical control of hybrid and monolithic microwave circuits, such as switches, attenuators, phase shifters and mixers, has been described by several investigators.[1-4] A PIN diode optical detector
has been fabricated and successfully tested on a GaAs MMIC substrate for the optical control of a phase shifter. However, the fabrication of the PIN diode on the MMIC chip requires additional processing steps, and thereby, increases complexity and cost.
