Multifunctional fish vision experiment device

Abstract

The invention discloses a multifunctional fish vision experiment device comprising an upper computer system, a control system, a driving system and a backlight plate group. The control system is connected with the upper computer system and the driving system, and the driving system is connected with back light plates; the upper computer system is used for adjusting experiment parameters and controlling the color, luminance, lighting time interval and the like of each backlight plate as well as the luminance and color in each area; the control system is used for selecting several preset common experiment schemes, adjusting and checking part of the experiment parameters and sending corresponding orders and data to a driving plate through obtaining the experiment parameters input by a laboratory technician; and the driving system provides constant currents for the backlight plate group by utilizing a constant current circuit. The multifunctional fish vision experiment device has the characteristics of being simple in structure and convenient to operate and avoiding noises in an experiment process.

Description

technical field [0001] The invention relates to a multifunctional fish vision experiment device. Background technique [0002] The eyes of fish can not only perceive the brightness and color of light, but also perceive the shape, size and movement of objects. The visuomotor response, phototaxis, luminescence, body color change, feeding, colony, reproduction, defense and other behaviors of fish are closely related to light perception. Therefore, it is of great theoretical and practical significance to study the light perception of fish. The research content on the visual ability and behavior of fish involves what fish can see, whether they can distinguish different colors and object shapes, the lowest and highest light intensity of visual response, visual distance, and the adaptability in bright and dark visual environments response etc. [0003] The black-and-white stripe test device in the past will produce noise when it rotates, which will affect the experimental result...

Problems solved by technology

However, the device cannot precisely control the output of the light source, and cannot carry out the persistence experiment of fish vision.

[0006] Later, there is a fish vision experiment device, which can realize more experimental schemes, is easy to operate, does not emit noise during the experiment, and the experimental conditions are controllable, but the light source of the device has a single color, and different color discrimination experiments cannot be done.

And this device is an annular fish tank with a diameter of 0.5m and a height of 0.35m, which has limitations in space and generally cannot be adapted to fish with a body length of 10cm or more.
