    Abstract: A tunable transmissive grating comprises a transmissive dispersive element, a reflective element/ and an angle θ formed between the two elements. A first optical path is formed according to the angle θ, wherein light dispersing from the dispersive element is directed onto the reflective element and reflects therefrom. At least one element is rotatable about a rotational center to cause a second optical path and thereby tune the wavelength of the light reflecting from the reflective element. Both elements can be rotatable together around a common rotational center point according to certain embodiments, and/or each element can be independently rotated around a rotational axis associated only with that element. According to some embodiments, the relative angle θ formed between the elements is held constant; however, in other embodiments θ can vary. A control system can be used to operate the device.

    Abstract: A miniature, flexible, fiber-optic scanning endoscope for nonlinear optical imaging and spectroscopy. The endoscope uses a tubular piezoelectric actuator for activating a cantilevered optical fiber from which pulsed light produced by a laser source exits and is directed to a target region through a micro-lens. The actuator is activated by two modulated signals that achieve two-dimensional beam scanning in a desired scan pattern. A double-clad optical fiber is employed for delivery of the excitation pulsed light and collection of emitted light received from the target region. The pulsed light travels through a core of the double-clad optical fiber, and the emitted light from the target region is directed into the core and inner cladding of the optical fiber and conveyed to a proximal end, for detection and processing. The emitted light can include multiphoton fluorescence, second harmonic generation light, and spectroscopic information, for imaging.

    Abstract: A line in a Raman spectrum scattered from a sample (18) is selected by a diffraction grating (20) and passed to a detector (26). The grating (20) may be based on an electrostrictive device and has a variable pitch. It is tuned about the selected Raman line under the control of an oscillator (28). The output from the detector (26) is analysed synchronously with the oscillation by a phase sensitive detector (34). This rejects background light and enables, for example, confirmation of the existence of the Raman line in the spectrum, and measurement of its height above the background. The variable pitch grating (20) may be replaced by a fixed pitch grating or a tunable filter, mounted on an oscillatory drive which may comprise electrostrictive or piezolelectric elements.
