Title: Douglas A Herr: Innovator in Infrared Sensor Technology
Introduction
Douglas A Herr is a notable inventor based in Lancaster, PA (US). He holds 2 patents that showcase his contributions to the field of infrared sensor technology. His innovative work has significantly advanced the capabilities of optical devices.
Latest Patents
One of Herr's latest patents is for an integrated ultra-sensitive infrared sensor. This apparatus is a miniature assembly that detects very low power infrared radiation and produces an electronic signal. The incoming infrared is combined in a wavelength multiplexer with high energy light from a laser chip and passed through an upconversion crystal, where their frequencies are added together. The higher frequency, lower wavelength light is then directed to a miniature blue sensitive photomultiplier tube that generates an electrical signal. A thermoelectric cooler is used to control the temperature of the laser chip, and the entire device is assembled into a package approximately the size of a cigarette pack. Another significant patent focuses on optical devices having improved temperature stability. These devices utilize non-centric crystals, such as lithium niobate, and methods for making and using them. The devices provide improved temperature stability compared to conventional devices using non-centric crystals. This stability is achieved by etching the surface of a non-centric crystal to a depth of less than about 300 angstroms, which reduces the magnitude of change in bias voltage required to maintain an optical crystal at a pre-selected operating point.
