Optical-resolution photoacoustic microscopy (OR-PAM) is an emerging technology capable of imaging optical absorption contrasts in vivo with cellular resolution and sensitivity. Here, we provide a visualized instruction on the experimental protocols of OR-PAM, including system configuration, system alignment, typical in vivo experimental procedures, and functional imaging schemes.

Optical biosensors utilize light to detect the binding of a target molecule. These sensors can utilize a label molecule, which produces a measurable signal such as fluorescence, or these sensors can be label-free and use the changes in optical properties, such as refractive index, to sense for the binding of the target molecule. This video introduces both label and label-free optical biosensors, demonstrates their use in the laboratory, and shows some applications of the technology.

FAQs
Optical efficiency falls when light is absorbed, scattered, reflected at surfaces, or misdirected by imperfect alignment. These mechanisms reduce the useful power or signal that reaches the next stage, even when the source produces sufficient light. Separating the losses helps engineers identify whether material choice, surface behavior, focusing performance, or alignment is limiting system output.
Different components influence optical efficiency through different functions. Transmitting elements must pass light, reflective elements must redirect it, focusing elements must concentrate it, and converting or detecting elements must preserve useful signal during those operations. Evaluating each function separately helps reveal where performance is lost and supports targeted component optimization rather than treating the system as a single unit.
Alignment determines whether light follows its intended path through the system. Even well-designed transmitting, reflecting, focusing, converting, or detecting components can deliver less useful signal if their positions or orientations do not guide light correctly. Engineers therefore consider alignment alongside component selection and optical design, because reducing misdirection can improve output, signal quality, and overall reliability.
Engineers evaluate performance by examining how much useful optical power or signal survives the system and by identifying the losses introduced at different stages. They can relate observed limitations to absorption, scattering, surface reflection, focusing, conversion, detection, or alignment. This analysis guides material selection, optical design changes, and component optimization before a system is finalized.
Optical efficiency analysis supports a broad range of engineered technologies, including imaging devices, fiber-optic links, lasers, solar technologies, and sensors. The relevant performance goal varies by system: engineers may seek stronger delivered signals, better energy use, improved detection, or more reliable operation. Comparing losses across these applications helps adapt optical design to the system’s intended function.
Improving optical efficiency helps engineering systems use received light more effectively while limiting losses that weaken signals or waste energy. The resulting analysis informs material selection, component optimization, and overall optical design. In photonic technologies, these choices support better energy use, signal quality, and reliability, providing a practical link between loss analysis and technology development.
