Title: Howard J Field - Innovator in Photoconductive Detection
Introduction
Howard J Field is a notable inventor based in Malvern, GB. He has made significant contributions to the field of photoconductive detection, particularly through his innovative patent. His work addresses the challenges associated with extracting the photosignal component from detector output while excluding the pedestal bias response.
Latest Patents
Howard J Field holds a patent for a "Method of biasing a photoconductive detector and detector apparatus." This invention tackles the problem of effectively extracting the photosignal component from the output of a detector. To achieve this, Field applies a time-varying bias signal to each element of the detector. The duration of this signal is chosen to be long compared to the photocarrier lifetime, and its amplitude is sufficient to cover a non-linear portion of the responsivity characteristic of each element. The bias signal includes a d.c. component, allowing it to operate around a point of asymmetry on the responsivity characteristic. The photosignal component can be removed through time averaging or harmonic separation, or alternatively, the bias signal may be modulated for extraction via detection of the demodulated signal. He has 1 patent to his name.
