OSA Technical Groups Poster Award

OSA offers several technical groups for members working in biomedical optics, which provides them with the chance to connect with colleagues working in their area of specialization. As part of this congress, several of these technical groups are supporting an award for Best Poster Presentation for students and recent graduates. Individuals interested in being considered for this award should complete the application form at https://forms.gle/bJXvUEBrgDWVLXW68. Participating technical groups include:

Therapeutic Laser Applications

This group focuses on the use of lasers in surgery or in other treatments of disease. This includes the use of lasers as surgical tools for tissue cutting, welding, and coagulation, as well as the use of optics to initiate cell-damaging photochemical reactions for the treatment of diseases such as cancer. In addition, optics, spectroscopy, and imaging provide unique tools that may allow real-time diagnostics of the efficacy of clinical procedures. For many of these applications, the development of optical tools for appropriate light delivery, especially for fiber-based or endoscopic delivery to tissues that are not directly accessible, is critical. In addition, this group emphasizes basic science studies of the mechanisms by which light can affect tissue in adverse or therapeutic ways.

Tissue Imaging and Spectroscopy

A variety of techniques are being applied to in vivo optical imaging and spectroscopy in the case where the light is scattered many times as it passes through the sample. This group focuses on the use light to form images of tissue using diffusely scattered light or to determine tissue properties through spectroscopic measurements. Optical techniques used for both imaging and spectroscopy include reflection, absorption, fluorescence, phosphorescence, Raman, and the photo-acoustic effect. Such techniques are an essential tool for biomedical research involving small animals and hold great promise for clinical tasks such as breast cancer imaging, brain mapping, endoscopic imaging, and real-time feedback on efficacy during therapeutic procedures.

Microscopy and Optical Coherence Tomography

Optical tools are well suited to the study of biology because the attainable spatial resolution matches so closely to the length scale of cells and sub-cellular features: the spatial scale over which many events in normal and disease-state biology are occurring. Microscopic imaging continues to play a dominant role in medicine and biology, driven by the continuous advances in terms of imaging capabilities and contrast mechanisms. This group emphasizes the development and application of new techniques for micrometer-scale structural and functional imaging of biological systems. Among the efforts of this group are the development and application of methods that optimize the optical examination of cellular and tissue biology through increased spatial resolution, higher acquisition speeds, improved penetration depths and maximized contrast. Directions of interest include super-resolution microscopy, multimodal approaches, linear and nonlinear quantitative imaging, phase-sensitive detection of optical signatures and the integration of microscopy and OCT with endoscopic applications.

Imaging Optical Design

This group encompasses the design and characterization of traditional optical systems utilizing lens design, geometric ray-tracing, and physical optics modeling. The evolution and development of design codes and software to assist in designing components and systems are included here. Typical applications include astronomical telescopes, microscopes, cameras, stray light, and adaptive optics.

NonImaging Optical Design

This group encompasses the design and characterization of illumination systems using modeling techniques. Non-sequential design techniques, including both software and tailoring methods provide the tools to design efficient optical components that provide the desired distribution at the target. Typical applications include solar energy, lighting, and displays.
