APPARATUS AND METHOD FOR ELECTROMAGNETIC RADIATION SENSING

摘要

Systems, methods, and apparatus for providing electromagnetic radiation sensing. The apparatus includes a radiation detection sensor including a plurality of micromechanical radiation sensing pixels having a reflecting top surface and configured to deflect light incident on the reflective surface as a function of an intensity of sensed radiation. In some implementations, the apparatus has equal sensitivities for at least some of the sensing pixels. In some implementations, the apparatus can provide adjustable sensitivity and measurement range. The apparatus can be utilized for human detection, fire detection, gas detection, temperature measurements, environmental monitoring, energy saving, behavior analysis, surveillance, information gathering and for human-machine interfaces.

1. A radiation sensing apparatus, comprising:
at least one row of micro mirrors arranged along a first direction in a first plane, each respective micro mirror in the row of micro mirrors having a radiation absorbing surface and a light reflecting area positioned at an opposite side of the radiation absorbing surface, wherein the respective micro mirror is configured to rotate along a second direction in the first plane in response to radiation absorbed in the radiation absorbing surface; a light directing device configured to direct a respective light ray from a light source to the light reflecting area of the respective micro mirror; and an imaging surface facing the light reflecting area of the respective micro mirror to receive a reflected light ray of the respective light ray directed onto the light reflecting area of the respective micro mirror, the imaging surface positioned in relation with the row of micro mirrors to produce equal displacements of light rays reflected from at least two of the row of micro mirrors onto the imaging surface for equal rotations along the second direction in the row of micro mirrors.
