This paper discusses a model of a system for controlling the scanning mirror on an input–output active–passive system and the small mirror of a two-coordinate microscanner. A mathematical model of a two-circuit system for controlling the line of sight is constructed on the basis of type-II Lagrange equations, using Gilbert’s mixed method. Algorithms are developed and control laws are formed that provide the required accuracy and dynamic characteristics of the target-tracking regime. Digital modeling is implemented in the MATLAB environment. The model is verified from the results of adjusting a test sample. © 2017 Optical Society of America.

This paper proposes an optical layout for a monolithic spectrograph with a transmissive holographic diffraction grating. All the elements of such a layout are located on the surface of a single block of transparent material. Such an approach allows the design of the device to be simple and reliable and makes it possible to increase its aperture and to introduce additional correction of the aberrations. The use of a transmissive holographic grating in such a layout makes it possible to reduce the size of the layout, to increase its stability against external effects, to couple it with other optical systems, and to achieve high diffraction efficiency. The technique for designing the optical layout consists of determining its starting configuration from the conditions for correcting the main aberrations of a grating on a plane, followed by numerical optimization. The layout of a spectrograph for the 450-900-nm range is given as an example. The achievable image quality is demonstrated, and ways are presented to implement the proposed grating. © 2014 Optical Society of America.
