Frequently Asked Questions

A position-sensitive detector is a detector that can determine the position of incident light within its active area.

There are several types of position-sensitive devices, including position-sensitive photodiodes (PSDs), charge-coupled devices (CCDs), and quadrant photodiodes (QPDs).

Position-sensitive detectors work by measuring the distribution of charge generated by incident light within their active area. This information can be used to determine the position of the light.

The active area of a position-sensitive detector is the region of the device that is sensitive to incident light.

The resolution of a position-sensitive detector is the minimum resolvable distance between two points of incident light. It is typically determined by the size of the active area and the precision of the measurement electronics.

The linearity of a position-sensitive detector refers to how accurately it can determine the position of incident light over a wide range of intensities. A highly linear detector will produce a proportional response to changes in light intensity.

The dynamic range of a position-sensitive detector is the range of incident light intensities over which it can accurately determine position. A detector with a high dynamic range can detect both weak and strong signals.

The spatial resolution of a position-sensitive device is the ability to distinguish between two points of incident light that are very close together. This is typically limited by the size of the active area and the precision of the measurement electronics.

Position-sensitive devices are used in a variety of applications, including microscopy, spectroscopy, and precision alignment. They are particularly useful for measuring small changes in position or alignment over a large field of view.

Did You know?

Laser position sensing detectors (PSDs), also known as position-sensitive detectors, are highly sensitive optical sensors that can determine the position of a laser beam on a surface. PSDs are based on the principle of photoconductive effect, where a material's conductivity changes when it is exposed to light. When a laser beam is directed onto the surface of a PSD, the material absorbs the light, creating a charge carrier density that is proportional to the position of the laser beam on the detector surface. This change in charge carrier density is detected by electrodes placed at opposite ends of the PSD, which generate a voltage proportional to the position of the laser beam. PSDs are commonly used in a variety of applications, such as laser scanning microscopy, laser-based alignment systems, and industrial automation. They offer high accuracy and precision in determining the position of a laser beam, with typical resolutions of less than one micrometer. PSDs can also operate at high speeds, making them suitable for applications that require real-time position sensing. PSDs are available in various configurations, including linear and two-dimensional (2D) arrays. Linear PSDs can detect the position of a laser beam in one dimension, while 2D PSDs can determine the position of a laser beam in two dimensions. The size of the PSD surface area also affects its sensitivity and resolution, with larger PSDs typically providing higher sensitivity and resolution.
