Title: Distance-measuring device
Inventor: YAMASHITA KENICHI
IPC: G01S17/88
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To facilitate adjustment of focusing and aiming, and to improve laser life and reduce power consumption by driving a semiconductor laser so that frequency can be varied. SOLUTION: A time pulse generator 2 generates pulses at a certain time interval according to the instruction of a microcomputer(MPU) 1 and an oscillation frequency variable type laser drive machine 3 drives a semiconductor laser 4 so that frequency can be varied within the pulse time width. Since the semiconductor laser 4 is driven only within the pulse time width, the power loss of the semiconductor laser 4 is reduced and the life can be extended. Also, since the frequency can be varied, the focusing and boresighting of a lens can be easily adjusted by adjusting a laser beam from unvisible light to a visible light such as a red color. The laser beam emitted by the semiconductor laser 4 is projected on an object through a light transmission lens 7 and the reflection light is received by a light-emitting element 9 through a light reception lens 8.  A reception signal is inputted to an MPU 1 through an amplifier and the distance to the object is obtained by an operation. When the obtained value is equal to or less than a set value, an alarm is issued.

Certification of the air-fuel ratio correction coefficient which is a base of computation, and evaluation of the corrected result are also performed. Correction is carried out only when the result is in the allowable range. Control parameters such as basic jet period is thus made to be proper.
