Abstract
Provided for herein is a mirror including a substrate and a reflective coating, wherein the substrate is absorptive at a first wavelength and transmissive at a second wavelength, wherein the reflective coating is reflective at the first wavelength; and wherein the reflective coating is arranged on a first side of the substrate opposite a second side of the substrate; a first radiation source configured to transmit radiation at the first wavelength incident on the first side of the substrate; and a second radiation source configured to transmit radiation at the second wavelength incident on the second side of the substrate.
Claims20
An apparatus comprising:
- a mirror comprising a substrate and a reflective coating, wherein the substrate is absorptive at a first wavelength and transmissive at a second wavelength, wherein the reflective coating is reflective at the first wavelength;
- and wherein the reflective coating is arranged on a first side of the substrate opposite a second side of the substrate;
- a first radiation source configured to transmit radiation at the first wavelength incident on the first side of the substrate;
- and
- a second radiation source configured to transmit radiation at the second wavelength incident on the second side of the substrate.
A laser range finder comprising:
- a mirror comprising a substrate and a reflective coating, wherein the substrate is absorptive at a first wavelength and transmissive at a second wavelength, wherein the reflective coating is reflective at the first wavelength;
- and wherein the reflective coating is arranged on a first side of the substrate opposite a second side of the substrate;
- a first radiation source configured to transmit first radiation at the first wavelength incident on the first side of the substrate;
- a second radiation source configured to transmit second radiation at the second wavelength incident on the second side of the substrate;
- a telescope configured to receive the first radiation reflected from the mirror and the second radiation transmitted through the mirror and receive the first radiation returned from a target;
- and
- a detector configured to detect the first radiation returned from the target.
