An optical system for particle size and concentration analysis, includes: at least one laser that produces an illuminating beam; a focusing lens that focuses the illuminating beam on particles that move relative to the illuminating beam at known or pre-defined angles to the illuminating beam through the focal region of the focusing lens; and at least two forward-looking detectors, that detect interactions of particles with the illuminating beam in the focal region of the focusing lens. The focusing lens is a cylindrical lens that forms a focal region that is: (i) narrow in the direction of relative motion between the particles and the illuminating beam, and (ii) wide in a direction perpendicular to a plane defined by an optical axis of the system and the direction of relative motion between the particles and the illuminating beam. Each of the two forward-looking detectors is comprised of two segmented linear arrays of detectors.

System and method for particles measurement

Augmented reality glasses can include a first laser, a second laser, and a scanning mirror. The augmented reality glasses can also include a first polarization selective reflector and a second polarization selective reflector. The first polarization selective reflector is arranged to receive light from the first laser and reflect light received from the first laser at a first angle to the scanning mirror, and the second polarization selective reflector is arranged to receive light from the second laser and reflect light received from the second laser at a second angle to the scanning mirror. The augmented reality glasses can also have an eyepiece having an input coupling port arranged to receive light reflected by the scanning mirror.

Method and system for projection display with polarization selective reflectors

A head mounted display system configured to project light to an eye of a user to display augmented reality images can include a frame configured to be supported on a head of the user, a camera disposed temporally on said frame, an eyepiece configured to direct light into said user's eye to display augmented reality image content to the user's vision field, a reflective element disposed on the frame, and at least one VCSEL disposed to illuminate said eye, wherein the camera is disposed with respect to the reflective element such that light from the VCSEL is reflected from the user's eye to the reflective element and is reflected from the reflective element to the camera to form images of the eye that are captured by the camera.

Systems and methods for retinal imaging and tracking

An image display system can include a plurality of light sources configured to emit uncollimated light, and an eyepiece waveguide having an input port configured to receive beams of light at differing angles. The image display system also includes a scanning mirror having a surface with positive optical power configured to receive light emitted by the plurality of light sources. The surface with positive optical power is configured to collimate light emitted by the plurality of light sources to form a plurality of collimated light beams and direct the plurality of collimated light beams to the input port.
