摘要： A system for detecting ice formation on metal, painted metal and other material surfaces can include a transparent window having an exterior surface upon which ice can form; a light source and optics configured and arranged to illuminate the exterior surface of the window from behind the exterior surface; and a detector and optics configured and arranged to receive light backscattered by the exterior surface and any ice disposed on the exterior surface and determine the thickness of the ice layer. For example, the system can be used with aircraft by placing one or more windows in the wings of the aircraft. The system is used for a novel optical method for real-time on-board detection and warning of ice formation on surfaces of airplanes, unmanned aerial vehicles (UAVs), and other vehicles and stationary structures to improve their safety and operation.

摘要： A method for determining if tissue is malignant as opposed to non-malignant (i.e., benign tumor tissue, benign tissue, or normal tissue), In one embodiment, the method comprises irradiating a human breast tissue sample with light at a wavelength of about 310 nm and measuring the time-resolved fluorescence emitted therefrom at about 340 nm. The time-resolved fluorescence profile is then compared to similar profiles obtained from known malignant and non-malignant human breast tissues. By fitting the profiles to the formula I(t)=A.sub.1 e(-t/.tau..sub.1)+A.sub.2 e(-t/.tau..sub.2) one can quantify the differences between tissues of various conditions. For example, non-malignant human breast tissues exhibit a slow component (.tau..sub.2) which is less than 1.6 ns whereas malignant human breast tissues exhibit a slow component (.tau..sub.2) which is greater than 1.6 ns. In addition, non-malignant human breast tissues exhibit a ratio of fast to slow amplitudes (A.sub.1 /A.sub.2) which is greater than 0.85 whereas malignant human breast tissues exhibit a ratio of fast to slow amplitudes (A.sub.1 /A.sub.2) which is less than 0.6. This technique can be used with different excitation and/or emission wavelengths, and can be applied to the detection of malignancies (or other abnormal states) in tissues other than human breast tissue.

摘要： A rectal near infrared (NIR) scanning polarization imaging system uses NIR Photonic Prostatoscopy Analyzer (NIRPPA) for prostate cancer detection using light. The NIRPPA consists of a portable rectal NIR scanning polarization imaging unit and an optical fiber-based rectal probe capable of recording sets of 2D images of a prostate through rectum at different wavelengths and depths and obtaining a three dimensional (3D) image of the prostate and 3D locations of abnormal tissue inside the prostate. Diode lasers/light emission diodes (LEDs) with selected emitting wavelengths are used in the NIR spectral range from 650 nm to 2,400 nm corresponding to the four tissue optical windows (#I, 650 nm-950 nm; #II, 1,100 nm-1,350 nm; #III, 1,600 nm-1,870 nm; and #IV, 2,100 nm-2,300 nm). The fingerprint absorptions of water (H2O), Oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) in the prostate are used as native biomarkers for prostate cancer detection.
