Latest Patents

One of Beraldin's latest patents is titled "System and method of light spot position and color detection." This invention involves a position and color detection sensor designed to identify the position of a light spot in a light distribution that may include stray light components, such as those from other lasers or ambient lighting. The sensor utilizes two discrete response position sensitive detectors (DRPSDs). The first DRPSD calculates a raw estimate of the spot position, while the second DRPSD determines the actual spot position based on information from the first. Additionally, color detection is enhanced by dividing each pixel of the first DRPSD into elementary photocells, each covered with an appropriate optical filter. This innovative approach allows for the integration of two DRPSDs on the same chip, reducing production and alignment costs.

Another significant patent by Beraldin is the "Position sensitive light spot detector." This invention provides a method and apparatus for detecting the position of a light spot in a light distribution that may also include stray light components. The apparatus features a continuous response position sensitive detector (CRPSD) for determining a first centroid of the light distribution and a discrete response position sensitive detector (DRPSD) for determining a second centroid within a defined reading window. This multiple-stage approach combines the high resolution and speed of traditional CRPSDs with the accuracy of DRPSDs under variable lighting conditions.
