Improved fluoresced imaging (FI) and other sensor data imaging processes, devices, and systems are provided to enhance display of different secondary types of images and reflected light images together. Reflected light images are converted to a larger color space in a manner that preserves the color information of the reflected light image. FI or secondary images are transformed to a color range within the larger color space, but outside the color area of the reflected light images, allowing the FI or secondary images to be combined with them in a manner with improved distinguishability of color. Hardware designs are provide to enable real-time processing of image streams from medical scopes. The combined images are encoded for an electronic display capable of displaying the larger color space.

Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available. Comparing simultaneous infrared and visual images of an unknown item, such as bullet or shell casing, can detect illumination-induced artifacts in the visual image prior to searching the visual database, thereby reducing potential erroneous matches. Computer numerically controlled positioning of the toolmark relative to imaging sensors which use fixed focus optics with shallow depth of focus, varying focus distance and orientation systematically to construct a sequence of images, maximizes reliability of resulting images and their comparisons.

An image acquisition system has a computer and one or more imaging devices coupled to the computer. Each imaging device has a device memory and is capable of capturing a digital image and storing the image in its memory. An image device manager is implemented in software on the computer to control operation of the imaging devices. The image device manager presents a user interface (UI) within the familiar graphical windowing environment. The UI has a context space that pertains to a particular imaging context (e.g., scanning, photography, and video). The UI also has a persistently-visible imaging menu positioned within the context space that lists options particular to the imaging context. For example, if the context space pertains to the digital camera context, the menu lists options to take a picture, store the image on the computer, send the image in an email, and so on. In the scanner context, the menu lists options to select an image type, preview an image, send the image to a particular destination, and scan the image. The image acquisition system also includes a set of application program interfaces (APIs) that expose image management functionality to applications. The APIs enable applications to manage loading and unloading of imaging devices, monitor device events, query device information properties, create device objects, capture images using the devices, and store or manipulate the images after their capture.

A novel arrangement of Schwarzschild Cassegrainian objective coupled with a far-field visible imaging system that does not interfere with the interrogating (IR) beam is introduced. Typical (IR) microscopes that incorporate a Cassegrainian objective have difficulty in locating desired target sample regions based on the inherent limited field-of-view. Because commonly applied visible imaging accessories upstream must use the same numerical aperture based on the reflective geometry, such systems also suffer a limited field of view. To overcome such difficulties, the novel embodiments herein involve placing a visible camera with its optical axis collinear with the IR and primary visible beampath of the microscope but outside the optical path that provides the (IR) image magnification.
