摘要

Elements of spectroscopic continuous-wave, frequency-modulated ladar (CW-FM-ladar) concept based on principles of both CW-FM-range-finding and modulation spectroscopy, and also on modern techniques of optical signal transmission, reception and processing are presented. Features of heterodyning methods for ladar echo-signal reception are considered. The comparison of CW-FM-ladar with CW-FM-range-finder and incoherent pulse lidar is carried out. Estimations of the achievable signal-to-noise ratio, the operation range and the range resolution are performed using frequency-dependent parameters of the transmitting and receiving subsystems. Preliminary experimental results on the range-finding subsystem characteristics of the CW-FM-laser diode (LD) -ladar are discussed.

7. Occupational therapy intervention with a child is based upon an understanding and appreciation of normal development. Knowledge of current concepts and theories related to child development is essential when occupational therapist evaluates children. This background information helps therapist to plan intervention for the child. The aim of this study is to make observation video about development of about one year old child. The purpose of my study is to help occupational therapy students learn about child development. My study is practice-based thesis. It includes product, which is the observation video and study rapport. I describe my whole process in my rapport. The process includes different kinds of stages. First, I studied those theories of child development, which are used in the studies of occupational therapy for children. These theories are Moseys Developmental Frame of Reference and the theory of development according to Sensory Integration Theory. These theories are the frames of reference of my study. I organize the child development areas according to child occupations and skills. Then I start to plan, film and edit my video based on the theories of child development and the principles of making a video. In my rapport I describe all the stages of my study and explain the sequence and the content of the stages. I also evaluate the process of my study. In the observation video you can see those stages of development where about one year old child is based on the frames of reference, which I have used in my study. I believe that my observation video can at least be good for inspiring occupational therapy students learning about child development. Keywords child development, learning, observation video [O] .
