A photo-acoustic polarimetric remote sensing apparatus includes a telescope that directs visible light photons from an object. A polarizing beam splitter is in optical alignment with the telescope. The polarizing beam splitter has first and second pathways corresponding to first and second polarization states, respectively. The first and second pathways are substantially perpendicular. A first photodetector is in optical alignment with the first pathway, and a second photodetector is in optical alignment with the second pathway. At least one processor is in communication with the first and second photodetectors. The at least one processor generates a signal corresponding to a degree of linear polarization of the photons over time, and the signal is indicative of an acoustic signature of the object.

An optical device for viewing a scene or subject while, at the same time, digitally recording images corresponding to the scene or subject being viewed. The optical device includes a housing supporting an eyepiece, an objective optic, and a prism assembly. The prism assembly is located along an optical path between the objective optic and the eyepiece. The prism assembly comprises a first prism and a second prism. The prism assembly allows the user to digitally record images corresponding to a scene or subject being viewed by the user. Both still images and video images may be digitally recorded. The prism assembly inverts the light traveling along the optical path so that the orientation of the image being viewed is consistent with the actual orientation of the scene or subject. The prism assembly allows the optical device to be shorter and more compact for a given magnitude of magnification.

A four color separation endoscope prism includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an infrared (IR) component. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area.

An endoscope system includes: a generating means generating a compositing mask that serves as compositing ratios of the corresponding pixels between a pair of images acquired by simultaneously imaging two optical images having different focus positions, into which a subject image is divided on the basis of the ratios of contrasts; a correcting means subjecting compositing masks generated for pairs of images acquired in time series, to weighted averaging for respective pixels, thus generating a corrected mask; and an compositing means compositing the two images according to the corrected mask. The correcting means subjects the compositing masks to weighted averaging by performing weighting such that the percentage of the past compositing masks is higher at pixels constituting a static area and an area having contrast lower than a threshold than at pixels constituting a moving-object area or an area having contrast equal to or higher than the threshold.
