Abstract: An ultraviolet sensitive video camera is disclosed. The camera may have an input window and a bandpass filter. The input window may receive into the camera ultraviolet radiation reflected off of a subject. The bandpass filter may filter the ultraviolet radiation received into the camera through the input window. The bandpass filter may have a passband centered at about 254 nm and a bandwidth of about 1 nm to about 100 nm. The camera may also have an image sensor and at least one controller. The image sensor may collect the filtered ultraviolet radiation passing through the bandpass filter and generate an output based on the collected ultraviolet radiation. The at least one controller may be configured to generate video display signals based on the output of the image sensor.

Abstract: Systems and methods are disclosed for capturing images of latent evidence such as a latent fingerprint provided on a curved or irregular surface of an object. According to certain embodiments, a latent fingerprint provided on a curved or irregular surface of an object is illuminated by a UV lamp. An aspect of the latent fingerprint is specularly reflected from the surface of the object and captured by an image capturing device. In various embodiments, the UV lamp is repositioned, or the object is rotated and translated, such that a second aspect of the latent fingerprint is then specularly reflected from the surface of the object and captured by the image capturing device. The first and second images are then integrated by performing a pixel-to-pixel comparison of corresponding pixel data in the captured images. A device is also provided for rotating and translating the object for use in the disclosed embodiments.

Abstract: A corona detection device includes a bandpass filter having a primary passband that includes at least wavelengths in the range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in the range of about 675 nm to about 850 nm. The corona detection device also includes an image intensifier in optical communication with the bandpass filter. The image intensifier is configured to generate an image based on radiation passed through the primary passband and the secondary passband of the bandpass filter.

Abstract: An ultraviolet radiation emission unit includes a housing and an aperture located on the housing. A radiation source includes a light emitting diode configured to emit radiation having a wavelength within a range of about 240 nm and about 280 nm. A radiation reflector is disposed proximate to the radiation source and configured to direct the radiation emitted from the radiation source through the aperture in the housing.
