Abstract:
Abstract The paper investigates the influence of the insulation resistance of the responsive elements and the guard ring of a silicon 4-quadrant photodiode on its dark currents. It was found that a decrease in the insulation resistance leads to an increase in the dark current of the guard ring and responsive elements. It was found that the insulation resistance deteriorates due to the formation of surface inversion layers at the interface Si-SiO2. A method of increasing the insulation resistance of the active elements of the photodiode by etching oxide in the gaps between the responsive elemen

Abstract:
The sun vector is commonly used for defining a satellite attitude and many types of sensors exist for its determination. A fine pinhole sun sensor type was chosen and designed for HORYU-IV nanosatellite of Kyushu Institute of Technology. This sensor has a round-shaped hole and uses commercial off-the-shelf silicon photodiode, which consists of four small sensitive elements arranged close to each other. This type of sensors commonly uses look-up tables for providing high accuracy, which requires a large amount of data to be saved. Polynomial methods for sun vector determination were considered

Abstract:
In an optical tweezers system, the output signal of a photodiode quadrant detector and the temperature in a sample cell are two key factors for the quantitative measurements of mechanical properties of living biological objects such as cells, organelles and macro-molecules. In order to enhance the output of a quadrant detector and effectively control the temperature in a sample cell, the dependence of the temperature in the sample cell and the output of the quadrant detector for different illumination conditions are studied. The results show that appropriate illumination conditions can ensure

Abstract:
Silicon quadrant p-i-n photodiodes of different concentrations of diffused phosphorus in the n+- layer were fabricated. The experimental curve of phosphorus impurity distribution along the depth of the diffusion layer is obtained. The influence of charge carrier concentration in this layer on the dark currents of responsive elements and the guard ring was studied. Volt-ampere characteristics of photodiodes were measured. It was seen that when the surface resistance of the n+-layer decreases, the dark currents decrease, the samples with a surface resistance of 1,9 – 2,4 Ohm / □ have approximate

Abstract:
A system has been developed and tested for the optical noncontact measurement of displacement which consists of a light source, an objective lens, a quadrant pattern and a quadrant photodiode. The principle is based on the detection of contrast variation of a projected pattern. This system uses an one-axis method and shows good characteristics, in particular that it is not influenced by the color and inclination of the surface. The dynamic range in the measurement is 150μm with vertical resolution of 1μm. The principle of the method is verified with experimental tests.

Abstract:
A 4.2 kW solar furnace heliostat was interfaced with a closed-loop control system to manipulate the azimuth and elevation rotational degrees of freedom to continuously align a solar concentrator with the sun. A QP50-6SD2 quadrant photodiode laser beam positioning device, developed by Pacific Silicon and Sensor, was modified to sense the orientation of the sun. The quadrant photodiode was mounted inside a dark box with a pinhole aperture and mounted so that when the heliostat reflects light along the desired axis, the quadrant photodiode relays balanced error signals. These error signals were i
