A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookPhotometry: The Answer to How Light Is Perceived: Simply put, photometry is the measurement of visible light based on the response of the average human observer. How that definition translates into technically correct quantification methods is the focus of this article.That portion of the spectrum that the eye can see — and its rainbow of colors — is rather small, covering approximately 360 to 830 nm. What colors we perceive depends on wavelength, while...Photonics HandbookImaging Colorimetry: Accuracy in Display and Light Source Metrology: CCD-based instruments provide accurate photometric and colorimetric data for each image pixel, which enables precise characterization of displays, instrument panels, light sources and luminaires for parameters including color, luminance, uniformity, contrast, Mura and defects, and view angle performance.The market for flat panel displays (FPDs) has undergone tremendous growth, driven mostly by increased demand for televisions, cell phones, computers, digital cameras and MP3 players.
