Biography:
He was born on November 8, 1937 (according to other data of 1936) in the Kapryzka village of the Orel region of the Russian SSR in a large family of workers of the collective farm. The family had five children.
In 1955 he graduated from high school in Gvardejsk city of Kaliningrad region of the Russian SSR.
In 1960 he graduated from A. M. Gorky Kharkiv State University. In 1960 he entered the postgraduate studies of the University, which he graduated in 1963.
In 1964, as an employee of the Observatory at A. M. Gorky Kharkiv State University, he designed a spectrogelioscope - a spectrogelograph, previously created by Barabashov M. P. and Ponomarev M. G., a photoelectric device for adjusting the center of the line to the gap, which contributed to a significant progress in observations in the line K 232 СаII.
Together with Chekird A. T., Yevsyukov M., Fedorets V. A., Tsvetkova V. S. studied in detail the photometric properties of separate formations of the lunar surface.
In 1965 he defended his Ph.D. thesis on the Law of Reflection of Light by the Lunar Surface at the A. M. Gorky Kharkiv State University.
With the beginning of the study of the moon and planets with the help of automatic astronomical stations, along with Yezersky V. Y. and Psariev V. O., they conducted a fometric survey of soil samples from the moon, collected by the AMS "Luna-16", "Luna-20" and "Moon- 24".
In 1964, L. A. Akimov performed at the Astronomical Observatory of the A. M. Gorky Kharkiv State University, independently of V. S. Etkin, after conducting similar measurements, he discovered the effect of coherent backscattering amplification in the optical range, that is, he was the first to find for those times, a strange oppositional burst of brightness in light materials.
He was the head of the expedition of the staff of the Department of Astronomy and three students of the A. M. Gorky Kharkiv State University on the outskirts of the Esil settlement of Tselinogradskaya region of Kazakhstan on the observation of the solar eclipse on September 22, 1968, for the purpose of conducting cinematographic observations of the spectrum of the chromosphere in areas near the lines D3 HeI, D 1, D2 NaI, H and K CaII. They were specially designed for the expedition impure spectrograph, which was built by the mechanics of the Observatory L. V. Pavlenko and V. L. Pavlenko with participation at that time still a student of A. M. Gorky Kharkiv State University Crystal V. A., and which was successfully applied.
Together with other employees of the astronomical observatory of A. M. Gorky Kharkiv State University, he participated in observations of a total solar eclipse in Chukotka in July 1972.
In 1987, together with the work of GEOHI staff members of the USSR Academy of Sciences, these studies were marked by a bronze medal of the USSR Academy of Sciences. Together with Yezersky V.Y., Yevsyukov M. M. and Shkuratov Yu G., he performed a large series of works on establishing a connection between the optical and geological-morphological properties of the lunar surface. Taking part in the creation of the "Atlas of the Moon's Back Side" Together with Shkurutov Yu. G., Yevsyukov M. M. and Psariev V. O. performed mapping of the visible hemisphere of the Moon and its individual parts, as well as the boundary zone and the reverse side of the Moon. Together with Shkuratov Yu. G. and Tishkovets V. P., developed an interplateation of the oppositional effect and polarization properties of non-atmospheric celestial bodies and scattering of light by non-spherical particles. As a result of multi-year work, he created the "Reference Catalog of Optical Characteristics of Selected Areas of the Lunar Surface."
In 1987 he became the winner of the Barabashov prize of National Academy of Sciences of Ukraine.
In 1989 scientist received a Ph.D. degree in Physics and Mathematics, having defended his doctoral dissertation "Investigation of the Law of Reflection of Light by the Lunar Surface." astronomer worked as a leading researcher at Kharkiv University. He was the head of the Department of the Moon and the planets of the Astronomical Observatory.
He developed an empirical formula that characterizes the distribution of brightness on the disc of the Moon, which was later named after the name of the astronomer.
Astronomer died January 30, 2017.
Specialist in photometric studies of the Moon and the Sun. L. A. Akimov observed (photographed) the Moon for 25 years. Akimov's law is known to reflect light from extremely rough surfaces.
His name is the small planet 18750 "Leonidakimov" of the solar system.
