Designs for mitigating retroreflections in night vision systems are described. The designs described herein use diffraction gratings. A diffraction grating diffracts input light into several beams with different directions. A grating may be configured to transmit input light passing through an aperture stop towards the focal plane array (FPA), and to deviate reflections arising from the FPA in response to the input light outside aperture stop. Deviation of light may be obtained by designing the grating so that the majority of the total diffracted energy is concentrated in a single diffraction order while the energy in the other orders is limited. The diffraction order in which the energy is concentrated may be any diffraction order other than the zeroth order (the un-diffracted order), including for example the first order, the second order, the third order, etc. A grating may be formed as a discrete component or monolithically with the FPA.

High resolution optical spectrometers suitable for low illumination environments notwithstanding the inverse relationship between spectral resolution and etendue are described. The techniques described herein rely on freeform lenses designed to eliminate (or at least reduce) spectral broadening caused by the finite range of incidence angles generated by a beam with high etendue. Performance of a spectrometer can be improved by compensating blue shift effects with a corresponding red shift——a wavelength shift in the opposite direction. This can be accomplished by steering rays having a greater angle of incidence towards regions of the filter characterized by larger wavelengths of transmission.

The systems and methods are passive in that they do not rely on transmission of radiation (whether radiofrequency, visible, infrared, ultraviolet, acoustic, etc.) to determine range. The systems and methods described herein may be used both in civilian and military applications. The present techniques allow users to determine range to moving targets, which is notoriously difficult to estimate using the human eye. The present techniques perform ranging to a target using artificial intelligence models, including object segmentation and pose estimation. Object segmentation may involve determining a dimension (e.g., height) of a specified target in an image, in terms of pixels. If there are multiple objects in the scene, range estimates may be calculated using object segmentation for each object. Pose estimation involves a machine learning technique that identifies sets of coordinates corresponding to joint keypoints.

A very strong selection mechanism is provided in a tunable vertical cavity surface emitting laser (VCSEL) by manipulating the laser threshold to be different for TE and TM polarization by a employing a subwavelength grating in the laser cavity. The laser selects the polarization with the lowest threshold. The grating does not diffract and does not add loss to the cavity. It works by creating a large birefringence layer between the semiconductor and air sub-cavities of the full VCSEL. Multilayer stack calculations show that this results in a lower threshold for the TM polarization over the TE. This subwavelength grating layer, in one embodiment, replaces the AR coating on the semiconductor surface.

TUNABLE VCSEL POLARIZATION CONTROL WITH INTRACAVITY SUBWAVELENGTH GRATING
A very strong selection mechanism is provided in a tunable vertical cavity surface emitting laser (VCSEL) by manipulating the laser threshold to be different for TE and TM polarization by a employing a subwavelength grating in the laser cavity. The laser selects the polarization with the lowest threshold. The grating does not diffract and does not add loss to the cavity. It works by creating a large birefringence layer between the semiconductor and air sub-cavities of the full VCSEL. Multilayer stack calculations show that this results in a lower threshold for the TM polarization over the TE. This subwavelength grating layer, in one embodiment, replaces the AR coating on the semiconductor surface.

A system for irradiating a microplate may include a modular light engine with one or more light emitting devices. The light emitting devices are configured to emit germicidal radiation to irradiate the microplate, which is configured to be positioned below the modular light engine inside a chamber of the microplate irradiation system. In this way, a uniform intensity of germicidal radiation may be output by light emitting devices, resulting in disruption of contaminating nucleic acids present in the microplate.

Method and system for tetrachloromethane synthesis
Methods and systems are provided for photochemically synthesizing tetrachloromethane in an industrial scale using a plurality of arrays or channels of light emitting diodes. A wavelength output by an SLM lamp is customized to bias the photochemical reaction towards a target reaction and target product and away from a side reaction and side product. The higher yield of the target product improved efficiency and reduces the need for complex purification for removal of the side product.
