The invention discloses an in-orbit calibration method for correcting self-radiation of a heat mirror of a microwave imager based on reference radiation. The method comprises the following steps: calculating an included angle between the heat mirror of the microwave imager and the sun; calculating the earth observation brightness temperature of the microwave imager; calculating the observed brightness temperature of the reference microwave radiometer; simulation brightness temperature of the reference microwave radiometer and the microwave imager is obtained based on radiation transmission model simulation; calculating an observation brightness temperature deviation and a simulation brightness temperature deviation, and calculating a system error between the reference microwave radiometer and the microwave imager; based on the system error, the included angle between the microwave imager heat mirror and the sun is adopted for function relation fitting, and the heat mirror self-radiation brightness temperature of the reference microwave radiometer is calculated; the included angle between the microwave imager heat mirror and the sun is calculated on orbit in real time, and the earth observation brightness temperature of the microwave imager is corrected based on the self-radiation brightness temperature of the heat mirror. The self-radiation of the heat mirror is solved in real time by taking double deviations of observation brightness temperature and simulation brightness temperature as constraints, and the problem that the temperature of the heat mirror of the microwave imager cannot be actually measured in orbit is solved.

A reflective waveguide includes a substrate comprising a plurality of partially-reflective prisms and an input hot mirror disposed at one or more partially-reflective prisms of the substrate. The input hot mirror is reflective to infrared light and substantially transmissive to visible light and is configured to incouple infrared light into the reflective waveguide. The substrate further comprises an incoupler configured to incouple display light into the reflective waveguide, an outcoupler comprising a first subset of the plurality of partially-reflective prisms and configured to outcouple the display light from the reflective waveguide, and an exit pupil expander comprising a second subset of the plurality of partially-reflective prisms and configured to guide the display light from the incoupler to the outcoupler.

A head-up display is proposed comprising an image generation device configured to generate a light beam (3) and an optical system separate from the image generation device, located at a distance from it, and configured to receive and transmit the light beam to a partially transparent plate. The image generation device comprises a light source configured to generate the light beam, a variable transmittance element array (10) configured to selectively receive and transmit the light beam, and a hot mirror (12) and a polarizer (13) placed in the optical path of the light beam downstream of the variable transmittance element array relative to the direction of propagation of the light beam, the hot mirror being placed upstream of the polarizer in the optical path.
