    Abstract: Advantage is taken of the fact that in optical navigation devices it is possible to measure the intensity of light impacting the pixel array of photo-diodes. Based upon such an intensity determination, a feedback signal is used to reduce the intensity of the light to a point where it is equal to or less than a predetermined value. In one embodiment, the discharge rate of a capacitive power supply is used to determine the intensity of the light source impacting the pixels. When the discharge rate is faster than a given amount the inference is that the light intensity is too great and power is reduced to the light source to reduce the intensity.

    Abstract: A light sensor protection system and method protects a light sensor system from a laser threat. The light sensor system has a sensor housing which contains optical elements disposed within the sensor housing and at a first end of the housing to converge light rays entering the housing at a focal plane. A focal plane array is disposed within the sensor housing substantially coincident with the focal plane. A means for protecting the light sensor system from a laser threat is disposed within the housing remote from the optical elements, the light rays, and the focal plane array. The method includes the steps of (a) providing a light sensor system as described above; and (b) protecting the light sensor system from a laser threat in the presence of a laser threat or upon a warning thereof with the means for protecting the light sensor system from a laser threat.

    Abstract: Two Fabry-Perot interference filters are used as tandum polarizers for a h-power laser beam counter measure in an optical scene. The scene radiation is directed on one polarizer; one plane of polarization of the laser beam is transmitted thereby and the other scene radiation is reflected to the other polarizer. The other polarizer transmits the other plane of polarization of the laser beam and reflects the other scene radiation to a photodetector, such as an image intensifier, infrared imager, television camera tube, or a human eye. The laser beam transmitted by the polarizers is trapped by absorbers and cannot harm the photodetector.

    Abstract: A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complementary and near complementary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complementary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined.

Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined. The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.
