摘要： Reflective front projection screens capable of projecting an image with enhanced contrast and a wide viewing angle in the presence of relatively high levels of ambient light are disclosed along with projection systems using the screens. The projection screens include a reflective polarizing element in combination with a diffusing element and/or glare suppressing element. The reflective polarizing element transmits light of one polarization state and reflects light of a different polarization state. The reflective polarizing element may be diffusely reflective or specularly reflective and the optical properties of the diffusing element and/or glare suppressing element may be selected based on the optical properties of the reflective polarizing element to further enhance image brightness and contrast. The projection systems preferably project an image using light of the polarization state that is reflected by the reflective polarizing element in the screen to further enhance brightness and contrast of the image.

摘要： A detector system, filter therefor, and method of making same is disclosed. The filter includes an interference element having a reflection band disposed primarily in the near infrared, and having a high transmission over most of the visible region. The filter also includes an absorptive element that absorbs light non-uniformly over the visible region. The filter when combined with a semiconductor photodiode or other suitable detector yields a detector system whose spectral responsivity closely matches the visual response of the human eye.

摘要： Reflective polarizers, which transmit one polarization and reflect the other polarization, have an extended red band edge in the off-axis transmission spectrum to control off axis color (OAC) hue. To control the OAC hue, the red band edge of the off-axis transmission spectrum, or OAC spectrum, is shifted beyond the boundary for red light, or to at least 600 nm. Even more preferably, the OAC spectrum is extended further into the red than any red emission peak of an associated lamp providing light into a system in which the reflective polarizer is used. The concept applies equally well to any type of reflective polarizer, such as multilayer reflective polarizers, cholesteric reflective polarizers, and the like. The resulting reflective polarizers are very useful for many different applications, such as liquid crystal displays.
