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.

Absorbing substrate mirror

Methods and systems for non-contact temperature measurement of an object on which is attached or etched a diffraction grating. The diffraction grating expands and contracts as the object expands and contracts upon there being a change in temperature of the object. Upon a light beam being received on the diffraction grating, the diffraction grating produces a pair of complementary light beams and one of the light beams is reflected back onto the diffraction grating and then onto the other light beam in a manner that causes the reflected light beam to propagate alongside and non-parallel to the other light beam. The resultant two light beams are thereafter impinged onto a camera at respective first and second impingement locations. The temperature of the object is then determined based on the separation distance between the first and second impingement locations.

Non-contact temperature measurement systems and methods

A laser system may include one or more of the following components: a power supply, a continuous wave pump laser, a fiber optic cable, a positive lens, a gain medium, a heat sink, and/or a Q-switch. The laser system may be used in a light detection and ranging (LIDAR) system such as a scanning LIDAR system. The laser system may be designed to operate at wavelengths that may be safe for human eyes.
