A principal area of Nanohmics’ expertise is in optics, electro-optic systems and instruments employing optical transduction or detection. A specialty is low-noise optical detection – Nanohmics has experience in engineering optimal architectures for low-signal-level optical detection in fluorescence, laser-radar, and remote-sensing applications.
Nanohmics engineers have experience in classical imaging optical system design and optimization, but specialize in novel whole-system designs that may include illumination from lasers and/or LED’s, advanced detectors and imagers, coherent imaging optics, interferometry, holography, or spectroscopy. A strong emphasis on physical-optics design principles, coupled with capable analysis tools from ray-tracing to wave propagation, ensures a successful project from concept to final test. A successful electro-optic system design often depends critically upon the electronic post-processing of the optical signals. Nanohmics engineering staff are specialists with low-noise analog amplification of detector outputs and the subsequent digitization and signal-processing algorithms that are used to extract meaningful results. We have designed and constructed many systems with embedded microcontrollers to direct the acquisition of data and perform simple digital processing. More complex problems might require a dedicated digital signal processor (DSP), and we have extensive experience with both the hardware and software engineering required to use these devices. At the end of the signal processing chain, a user must interact with the hardware and embedded software to achieve the desired results, and Nanohmics engineers have direct and relevant experience with both laboratory-based and end-user-based graphical user interface design and implementation, either on mobile platforms (PDA) or on a desktop PC.
