Disclosed are systems for transmitting and receiving a radio frequency (RF) signal and an optical signal. One system may include a communication terminal comprising a primary concave reflector providing a first focal length to a focal point, and a secondary concave reflector providing a second focal length to the focal point. The communication terminal may further comprise an optical transceiver facing the secondary concave reflector, and one or more RF transceivers facing the primary concave reflector. The optical transceiver may be configured to transmit and receive the optical signal via the primary and secondary concave reflectors through the focal point, and the one or more RF transceivers may be configured to transmit and receive the RF signal via the primary concave reflector. The one or more RF transceivers may be positioned adjacent to the focal point and offset from a path of the optical signal.

An eye-mounted device includes a contact lens and an embedded imaging system. The front aperture of the imaging system faces away from the user's eye so that the image sensor in the imaging system detects imagery of a user's external environment. The optics for the imaging system has a folded optical path, which is advantageous for fitting the imaging system into the limited space within the contact lens. In one design, the optics for the imaging system is based on a two mirror design, with a concave mirror followed by a convex mirror.

A tunable filter may include an input focusing optic, an output focusing optic, a linearly-varying filter located at a back focal plane of the input focusing optic and a front focal plane of the output focusing optic, an input angular scanning component located at a front focal plane of the input focusing optic configured to receive an input beam, and an output angular scanning component located at a back focal plane of the output focusing optic. The input focusing optic may receive the input beam from the input angular scanning component and direct the input beam to the linearly-varying filter, where a position of the input beam on the linearly-varying filter is selectable based on an angle of the input angular scanning component. The output focusing optic may receive a filtered beam from the linearly-varying filter and direct the filtered beam to the output angular scanning component.

An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.

A telescope includes an initial telescope comprising a concave first mirror and a convex second mirror that are configured so that they form, from a light beam coming from infinity, an image called the intermediate image in a focal plane called the intermediate focal plane, the intermediate image having a largest dimension along an X-axis perpendicular to an optical axis of the telescope, a segmenting module comprising a first set of n segmenting mirrors that are placed downstream of the intermediate focal plane and that are configured to divide the intermediate image obtained from the intermediate focal plane into n sub-images, a second set of n refocusing mirrors that are configured to reimage the n sub-images into n images in a focal plane of the telescope, the images being arranged in the focal plane so as to decrease the dimension along X containing the n images, a detecting device placed in the focal plane.

A see-through type display apparatus includes an image forming unit; a relay optical system configured to transmit an image provided from the image forming unit and to form a primary imaging image; and an optical combiner configured to reimage the primary imaging image transmitted from the relay optical system and to form a multi-depth plane. The relay optical system includes a lens; a polarizer arranged at an angle with respect to an optical axis and configured to reflect light of light of a first polarization and transmit light of second polarization therethrough; a condensing mirror member configured to reflect and condense light incident from the polarizer; and a polarization converter configured to convert a polarization of light transmitted between the polarizer and the condensing mirror member.
